We've housed our poultry in the most ramshackle strawbale huts you could imagine for the past four years, on a cold wide open windy prairie at 5300' elevation, but boy are they cheap, compostable and highly effective, and despite their humble digs, the mixed flock of layers, ducks and turkeys seem quite content!
Though not too exciting to look at, the strawbale huts we made for the poultry are amazingly warm and cozy for the birds. This morning the temp inside the various compartments was possibly 50 degrees, while outside it is -10 with a wind chill. The snow has drifted around the
chicken palace, so its like an igloo with 16" thick walls. This hut cost about $16.00 to build and the heat is free!
We use 18 bales for the hut (more to cover the various openings and create wind
shelters)....they are stacked two high in a sort of backwards "E" arrangement, only with three compartments...(hopefully you can visualize)...the opening of the compartments are oriented ALWAYS to the East......so the birds wake up to a warm morning sun, and the prevailing winds don't blow in. (On this note, any birdhouse you have will be much more bird friendly oriented with the opening to the east for the same reason) This keeps the shelter from cooking in the summer too, cause the sun never shines in from the south or west. The northern endwall of the E is stacked two bales high and long, so the north winds are blocked a bit from wrapping around into the shelter, and the extra length here blocks an opening that the lean-to door makes. For the top we used a couple of sheets of old plywood, with one cinder block on each piece for weight, just laying flat across the top(I move them aside, and reach in to the back to collect the eggs)... and at the back side (West) we added another 4x8 sheet of plywood as a lean-to shelter. This area is getting drifted, so the snow=more insulation for the entire structure, and it's keeping the snow from blowing in through the gaps in the bale walls. For the front doors more 4x8 plywood is used in a lean-to fashion, and we've also used OSB, whatever we scrounged up. When the weather started turning wintry cold, we used additional bales stacked two high strategically placed at the lean-to openings (south end) to block wind. Before dark I move the bales to block the openings completely, and they are snug and the heat builds up in there quite well. Other things we've noticed about using bales for shelter...when they get musty or start to break down, we take it all apart, and break the bales open. The birds are SUPER happy to kick all that old
straw up and around and
poop it up. They are our little mulcher fertilizers! Then we build a fresh one. They do tend to roost on the roof, and really poop
alot up there, but its pretty easy to pull the top off, scrape the poo off, and clean it up, putting the poo where we want it. Modifications I think would make this a
class A set up are a nesting box array that is built to fit into the strawbale stacked wall...sometimes the girls eat eggs, and I think that is because the nests are at ground level in the same space they rest in. I would try to build it to rest on the bottom tier, but come up to the same height as a second layer of bale wall, if that makes sense. I have also been considering building a shed roof piece that has poly carbonate for the straight eastern facing wall, and sheet metal for the shed roof, you could anchor this down by pounding in some t-posts at the N and S ends of the structure, and securing the roof to the posts. I also think you could use scraps of sheet metal on 2x4 frames for the roof and lean-to doors and they would be easier to wash down, and longer lasting! I've debated alot the virtues of a framed/plywood sided
chicken house...and while I think the mobility of a framed structure would be much more efficient, the strawbale huts are not bad to move with two of us doing the job, and they are such great shelter in the winter...for us that's at least half the year, that I'm not sure anymore I want to give this method up.
Oh PS...we have around 60 birds housed in this way. If you have less, make it smaller! (They'll stay warmer if there is just
enough room, not too much)
