Hay, I am in Vermont (brrr) where it is already a little late to be thinking about Winter. I live in a very tight urban neighborhood (Vermont urban = small town). It is legal to keep chickens, and my neighbors are happy with the idea. On my 1/8 acre urban lot, I have a small historical horse barn for the one-horse & carriage transportation of the 1890s, when the barn was constructed. The barn is two stories: on the first floor is my workshop + car parking. On the second floor, was the hayloft, and now I have various materials stored (wood, canoe, etc.). In the summer, my four chickens (now 6-7 weeks old) have a lightweight chicken ark (tractor). For the winter, I am thinking of this design, and would like any advice: I have an old car-top carrier that I got in a free pile, that is about 3.5 x 3.5' or maybe a little bigger. Put half of this on the floor of the second-floor of the barn, and stack haybales around it to make "walls." I will construct a top out of wood. When the chickens move inside, I will add hay as litter inside the car-top carrier, and continue to add it (deep litter) over the winter. In the spring, when thing start to thaw, put the hay from inside the car-top carrier into my compost bins, and save the hay-house walls for next year, provided they are not too stinky. This is my urban variation on this type of approach: http://sugarmtnfarm.com/blog/2005/12/winter-hen-coop.html Thoughts?
