Introducing: The Beta Family

June 30th, 2011 by Darren
The Beta Family: Steph, Darren and Maggie

Greetings from the Nauhaus

Hello all -

Greetings from the Nauhaus. As a brief introduction, we are the Beta Family – though you can call us Steph, Darren and Maggie (our mutt of unknown lineage). We have dubbed ourselves the Betas since we have taken up residence in the Nauhaus while the Alphas – Jeff, Jeannine and Jackson – have moved further north (for now) to tackle new challenges. As we’ve settled in over our first few weeks, we can’t stop smiling at how lucky we feel to be living in such a beautiful and peaceful place. We’re also humbled by all the blood, sweat and tears that were shed in its construction. We hope to honor every contributor’s hard work by sharing bits of our experiences in living at the Nauhaus while making our own contributions to its evolution as well (we’ve started that endeavor in the garden). We look forward to keeping in touch.

More Chicken Talk

February 11th, 2011 by beejay
Here are some answers to those questions Jeff

1.  and  2.
A chicken needs a minimum of 3 square feet. MINIMUM. But they thrive in much roomier environments. They do prefer roosting at least 18 inches of the ground.
Many people forget to make the coop comfortable enough for them to get in and out of and move around in. You want to make sure it’s high enough that you don’t have to be inside hunched over and that it’s wide enough for you to move around in comfortably. Also, you want to make sure that you set things up to make your life as easy as possible. That means being able to access the nesting box to easily get the eggs. It also means placing the chicken coop in a place where you have easy and quick access to water, feed, and electricity if necessary
Allowing an adequate level of space per bird also helps keep the humidity level in the coop to a minimum.
Build your poultry house to prevent possible injury to your birds. Remove any loose or ragged wire, nails, or other sharp-edged objects from the coop. Eliminate all areas other than perches where the birds could perch more than 4 feet above the floor. Remove perching areas such as window sills, nest box tops, or electric cords whenever possible. These extra measures could eliminate any injury to you or your birds and may prevent damage to the coop, as well
With chickens, always provide 6 to 10 inches of perch space per bird.
Nest boxes range a lot, the most common that achieves high rates of success is 12x12x14 (dxhxw). There is some playing room here but they need to be single bird sized and not bigger (secure feeling).
Side Notes
Some things to consider are securing the floor area so that no animals can dig under and reach the chickens. Also, you don’t want any fencing too wide. In fact, it should be small enough to prevent snakes from getting in.
Because of the importance of keeping things clean, you want to make cleaning your coop as easy as possible. Some things to consider are painting all of the walls, inside and out, and using linoleum flooring.
3.
I have some plans drawn up for our meeting tomorrow and I think that there shouldn’t be a door from the shed into the coop, I think they should share a wall but have separate doors.
Ample air movement without a draft is essential. Fresh air brings in oxygen while excess moisture, ammonia or carbon dioxide are removed the stale air moves out of the house. Dampness and ammonia build-up are a sign that there is not enough ventilation. For small coops windows or vents on one side of the house usually provide plenty of ventilation. Well-ventilated houses must also have plenty of insulation and a good vapor barrier. Failure to insulate or ventilate properly causes moisture to accumulate on the walls and ceiling in cool weather. Poultry can handle cold very well if they are dry. However, cool and humid conditions can create many health problems. Locate openings on the side away from prevailing winds. The south or east side is usually best. A sliding vent on a cupola would work well also.
4.
There isn’t a very good way to have this completely automated unless we rig up a timer than can water on a schedule that would take a long time to calibrate. So the best way is going to be running a hose from a sink/faucet in the yard into a 5 gallon size bucket every week or two. It should be pretty low maintenance. Below are some good possible options.
Option 1
The parts list is:
1 5 gallon bucket with lid
1 new oil pan
some 1.5″ PVC pipe, some fittings, PVC primer and cement, some gasket material, and a valve
To fill it just turn on the garden hose, open the valve and pour water in. The pipe is big enough to let the air out while you are filling it. When you get it full just close the valve and you are done.
The total cost was about $15 and the step-by-step construction with photos is on the blog link below. (a bit of a strange blog albeit)
To heat the water during the winter so that it doesn’t freeze requires only a 3 or 5-gallon aquarium heater run to the tank which costs $10-15. There is also the method of heating a tile box below the tank with an incandescent light bulb
Option 2
Basically the same design only with the Avian Aqua Miser attachment nipples on the bottom of the bucket, with the bucket suspended beak high. This could possibly be easier because it might be easier to keep the water from freezing if it isn’t in an open trough.
Place the bottom of the waterers and top lip of the feeders at the birds’ back height. This will keep the feed and water clean and prevent wastage. When possible, place the waterer in the outside runs. This helps to keep the humidity level lower inside the coop.
5.
For this problem I have a solution in the plans I drew up specific to our site plan. It basically entails an access to the nest boxes from the outside of the coop through a swinging lid. Below is a similar idea.

Chicken Talk

(owners of “Just Us Hens” in Portland, Oregon)

Why Raise Chickens?

• Easy and inexpensive to maintain (when compared to most other pets)
• Eggs that are fresh, great-tasting & nutritious
• Chemical-free bug and weed control
• “Manufacture” one of the world’s best fertilizers
• Fun & friendly pets with personality (yes, you read that right)

For Jeff, I suggest you raise a friendly dual-purpose chicken. If you want a chicken that will provide delicious tender meat for the table and lay great eggs, I recommend the Buff Orphingtons. They have a docile and sometimes affectionate disposition that makes them great around children. In addition, these birds are a beautiful gold so you can show them off to friends and family. Below is a link to a great blog about a family who raised 5 of them at home. One other good breed for your purpose is the Wyandotte (If you want variety)

Your local feed store will sell chickens, feed and anything else you may need. They can also give you advice on anything important you might be overlooking.

Chicken nutrition

Chickens are one of man’s closest domesticated friends and have grown to eat many of the foods we eat. But chickens cannot be assumed to just “get by” on anykind of food. They would probably “get by” on our junky minimum, but they won’t be as healthy as they could be, and they surely won’t be much good for egg laying, unless they are fed the basics of what they need. In addition, mold or salt in table scraps and old grains can quickly kill a chicken.

WHAT CHICKENS NEED (It’s simple!)
1. Grains (whole, living grains are way better than cracked, and a mixture is way better than pure corn)

2. Greens (grass! weeds! fresh veggie paringsfrom kitchen!)

3. Protein (in summer, they get enough bugs — but in colder weather they need a protein supplement, including perhaps the following: yellow-jackets from restaurant traps, soybeans, worms, milk, meat, fish meal)

4. Water, Water, Water.

It is very important to remember that chickens need lots of water, especially when laying. They can actually die of salt toxicity in a few hours if not given water at all times. A good way to ensure hydration is to put the water dish right by the door of their coop, where they can get it every time they pass by. They won’t drink dirty water; so make a point to keep it fresh.

About protein… Producing a huge capsule of protein in the form of an egg every day doesn’t leave much room for irregular or sparse protein consumption. A 5-ounce egg is to a five-pound chicken what a 9-pound egg would be to a person weighing 150 pounds (use your imagination). To produce this capsule of pure protein is basically something like giving birth to a baby, every day! Needless to say, that protein needs to be replaced through their diet.

Here is a recipe that will provide optimum nutrition during the winter and is simple to make. Of course there are feeds that can be purchased as well. It is important to note that this is an ideal type mix and there is definitely room for creativity as well as ways of making large batches at once and storing them.

GRAINS- Scratch grain mix, from feed store, containing many kinds of grain ($5/50 lb). Extra yellow corn (cracked) provides them warmth in the winter, so I’m told. Grains must never be wet and moldy, this can kill your chickens!

GREENS- Grass forage, garden clippings, kitchen trimmings (thrown in the compost pile near their coop)

PROTEIN- Soybeans, oats, and sunflower seeds or some nut/seed.

Every morning (quantity for 5 chickens): 1/3 cup of boiled soybeans (make a batch every week or so: Soak 2 cups of dried soybeans in three or four times the volume of water overnight; bring to a rolling boil in the same water for 15 minutes; Drain; Store in a fridge) mixed with 1 cup of instant oats, some sunflower seeds, milk or water to moisten. Crushed oyster shell can also be added to provide calcium (5$/50 lb).

When purchasing feed or grain it is good to note that it can lose its nutritional value over time, so purchase it fresh. Remember too, store feed away from moisture and direct sunlight. Immediately remove stale, rancid or moldy food from feeders.

Alleviating heat stress in chickens during summer months

Poultry are prone to heat stress during periods of high temperatures and humidity. While chickens do acclimate to heat over time, sudden heat waves can cause trouble. When under severe heat stress, production efficiency drops and mortality risk rises. All chickens are susceptible to heat stress, but particularly older birds.
A chicken’s normal body temperature hovers near 104 to 107 degrees Fahrenheit. It’s not difficult for them to maintain a healthy body temperature when the air is at least 10 to 15 degrees below that (89 degrees and below). Without sweat glands to cool their skin, birds rely on their respiratory system. Chickens pant to cool themselves, as the panting evaporates water from the throat to lower body temperature they become dehydrated.

Water is instrumental to chickens surviving hot weather. Have very cool, clean drinking water available at all times in accessible locations. Also, birds in heat stress are not inclined to eat during the heat of the day, digestion naturally produces heat, so feed chickens during the coolest part of the day. Keep chickens in a well-ventilated area with adequate air flowand provide shady areas if the birds are resting outdoors during the heat of the day. Regularly remove any accumulated litter from the chicken house, as decomposition produces heat, and removal also keeps pests to a minimum. Reducing radiant heat in the poultry house with adequate ceiling insulation is another good idea. Outside of the chicken house, tall grass and weeds restrict airflow; while bare ground can reflect heat into the house, so keep low cut grass to help to absorb the sunlight.

Keeping Chickens Healthy and Happy When It Gets Cold

As far as the hens are concerned, it’s not cold until it’s below freezing. When the hens are exposed to daytime highs below freezing, egg production usually plummets. However, it has to get a lot colder than that before the hens’ health begins to suffer. During freezing weather, egg production and hen comfort will be increased if they have plenty of (non-frozen) water to drink. If you don’t have piped water to the henhouse, I recommend using galvanized or rubber buckets/pans as waterers because plastic buckets split when they freeze. Try not to let the hens run out of feed in cold weather either. Also, the hens will be warmer during the day if they exercise. If they have been outside for the rest of the year they should be outside in the winter too. They’ll be warmer at night if they go to bed with a full belly too, feeding them later in day during the winter so they can digest into the night is a good idea.

As far as heating goes, it shouldn’t be necessary here. Don’t try to keep the house too warm either. In particular, don’t restrict ventilation in an attempt to conserve warmth. The hens produce so much moisture in their breath and droppings that restricted ventilation is at least as likely to lead to condensation and frostbite as warmth and comfort. Restricted ventilation can also cause ammonia build-up in the air, which is very bad for the chickens’ unusually weak lungs. On a local WNC forum one man stated that “My housing is very open and is highly ventilated. Cold snaps as low as 10°F-20°F reduce egg production but the birds remain healthy and active. My reading indicates that open-front housing is suitable for winter quarters even in New England.” So, As long as temperatures are above zero degrees Fahrenheit or so, the chickens should be pretty happy. Moisture seems to be a bigger issue in Jeff’s situation.

Lighting and Bedding

Straw works great for the beddinginside roosts. There may need to be a 2-3 inch groundcover of fine mulch or wood shavings to collect droppings that would be replaced annually. I am pretty sure that you can get wood shavings for like $3-$5 a bag at the local sawmill. You wont have much space to cover anyways since the chicken roosting box should be pretty small.

If your goal is to have a stable amount of eggs all year round a light would need to be installed in the coop to maintain a similar amount of “daylight” in the winter. Otherwise, having adequate ventilation and maybe a small skylight or window should provide for enough lighting in the coop.

And Finally…

Wear clean clothing when working with the birds. Wash hands thoroughly and frequently. This will help keep you and the chickens healthy.

Whatever the style, provide enough space for the number of chickens your structure will hold. An adequate number of nesting sites and perches will be necessary.

Typically your chickens will begin laying eggs between the twentieth and twenty-first week. They will continue to lay eggs for slightly over a year, and the number of eggs and their size will be best during this time.

Have Fun!

Cordwood in Kenai, Alaska

January 18th, 2011 by Strongwood

This is Mark & Chelsea in front of their cordwood home in Kenai, Alaska.  The walls are 14″ spruce with foam insulation in the center cavity between the two 3″ mortar beads.

Here are more photos of their two story home.  They used a log wizard to craft the beams, posts and rafter.

Alaska provides ample solar time to work during the summer, but in the winter it can be a challenge.

Nauhaus Prototype Update: We’re Done So Quit Askin’!

November 29th, 2010 by Clarke

Thanks to everyone who has pushed me for an update on the carbon neutral prototype house project. I’ve had my hands full and blogging just hasn’t risen to the top of the list. Stay tuned because I have six months of great research results on a number of fronts including compressed earth block floors and walls, site made earthplasters, and a simple purchased clay and sand earth plaster.

What everyone asks first, however, is “when are you gonna be done”? Let’s put that baby to bed once and for all: we’re done. We’ve received our Certificate of Occupancy from the city and are jumping through a few hoops for the bank (don’t get me started, gawd!). Our test family, Jeff/Jeanine/Jackson (JJJ), are moving in upstairs next week. We’re looking for someone to live in the downstairs apartment, and the Nauhaus think tank/office/lab will be moved to the downstairs office.

So from a real estate, taxes, and bank perspective, we’re done. However, the point of this research project wasn’t just to build a house, but to create a living lab and opportunity for study, so there is still lots of work that we’ll do. High on the list will be to complete the final blower door test to see if we will receive Passive House certification. In the next month or two, we’ll be completing a collaboration with Tom Rioux of Earthpaint to test a number of finish solutions for the earthen materials in the building. This is exciting work because in the end we’ll be able to specify commericially available products from Earthpaint to finish and seal compressed earth blocks and earthen plasters.

If you want to help us with our ongoing research, we still need support to realize our:

  • performance monitoring system
  • “urban homestead” landscape installation
  • 7KW photovoltaic system to make the project perhaps one of the first carbon neutral houses in the world

    Cordwood Hobbit Style House with round door and living roof in Wisconsin

    August 23rd, 2010 by Strongwood

    Dan and Jessi P. built every hairy footed hobbit-fanciers dream home.  A 16 sided cordwood home (in Wisconsin,) complete with post and beam framework, living roof, masonry stove/heater/bake oven, stained concrete floor and a round, green hobbit door.

    The work is artistic, attractive and very nicely done.  The bottle end  and cordwood walls are artistic, attractive and very well done.   The nasturiums on the floor add a touch of whimsy.

    Here is a quote from Jessi’s blog.

    “We’re proceeding apace with the walls, which look so lovely when they’re done – from a distance they look like stone. Labor intensive and messy, but beautiful. We also have the framework for the round green door done. So we’re looking hobbity!”

    Jessi ends her emails with the following quote:

    Not all who wander are lost.   J.R.R.Tolkien

    Here is another quote from Jessi.

    Subject: Cordwood House

    Hi Richard – glad you like the looks of our place! All told, if you count the tree cutting/peeling summer, it took us about 5 years, but the actual cordwood stuff we squeezed into about two and half months – we started in October and laid up the last bit of wall the second week in December two years ago with the aid of much tarping and space heaters . It’s sixteen sided on a floating slab. The logs are 18 inches with loose fill insulation in the cavity. They are a mix of hemlock, spruce, and red pine which we took for the most part off the property. Our masonry heater was done by Gimme Shelter Construction over by you and then faced by a local mason, Wayne Kostka. Don was partially right in his comment – even on the coldest days this winter we were comfy with two fires a day, and it has stayed cool enough this summer that we haven’t bothered to move the window air con over from our old house. The roof is 6-8 inches of dirt over an Enkadrain drainage layer. Sedum we put in last fall has spread nicely and we put in another couple pounds of cuttings this summer, so in a few years when we’ve worn out the weeds it should be a nice low maintenance roof. All the rain we’ve had this year has given it a good test

    To Jessi & Dan:

    Kudos, congrats and thank you for sharing your wonderful cordwood home.

    Nauhaus Prototype Gets Plastered

    July 13th, 2010 by Clarke

    Exterior and interior plastering is underway on the carbon neutral Nauhaus prototype.

    The interior surface of the hempcrete walls has a base coat of earthen plaster consisting of sub-soil harvested from the construction site and mixed with sand and water. The mix was chosen after testing sixteen different compositions, a process spearheaded by intern Shannon Levenson. Earth plaster serves the Nauhaus prototype mission because it requires almost no energy to make or transport, and therefore has very little carbon emissions associated with it. In addition, earth plastering is fairly easy to learn, requires few tools, and is instantly gratifying, both because it’s beautiful at any skill level and very similar to playing with mud pies, a therapeutic experience that many adults realize they have been neglecting for too long. Whatever the reason, the earth plastering process attracted volunteers and interns like flies to…well, compost.

    The exterior wall surface has been covered with a base coat of lime-based plaster supplied by Lime Technology as part of the hempcrete wall system. Both interior and exterior plasters were applied directly to the hempcrete which proved to be an excellent plaster substrate. Fiberglass mesh, similar to mesh drywall tape, were embedded in plaster over any joints or cracks in the hempcrete. Together these plasters over hempcrete create a vapor permeable wall system, sometimes called a “breathable wall”. The idea is to create a wall that is open to taking on and giving off water vapor in response to humidity levels in the air inside or outside the building.

    We believe vapor permeable walls will last much longer and help create better indoor air quality than cavity wall systems that dominate US residential construction. As any builder will tell you, it’s pretty much impossible to keep water out of walls. Permeable walls are designed with the idea that it’s okay if some water gets in as long as it can get out just as easily and won’t cause any damage in the process.

    radioMike Figura and I did an interview about the Nauhaus prototype with Ned Doyle for his radio show, “Our Southern Community”. Okay, the interview was in February and I’m just getting around to listening to it. I’ve been busy, so sue me.

    Anyway, this is still accurate and has good information about our work, though some things have changed. For example, Mike now wears a tie.

    Nauhaus Primer: Talking Head About Carbon Neutrality and the Nauhaus Prototype

    June 5th, 2010 by Clarke

    We recently recorded this video intended as a draft to help us work on our public spiel. It needs a lot of work, but I thought I’d post it anyway because it’s a fairly thorough introduction to what we’re doing generally and the prototype in particular.  Just pretend you’re in high school and lunch is next period…Go generic sports team with some sort of mammal as its mascot!
