I got a book from the library on chicken coop designs and found a very interesting one using square hay bales. They stacked the hay bales like a giant square igloo. In a farm magazine, I saw a round bale drilled out and used for a dog house. The owner said the hay kept his dogs cool in the summer and warm in the winter. My husband and I are thinking of doing the hay bale coop. Has anyone seen this or done this before? We are currently doing the deep litter method in a old shed by the house. We want to move the chickens away from the house because our front porch is full of poop! We don't have the resources to build a new coop but we do have hay. However, I do like the deep litter method.... My question is, how would I do the floor? Would I do the deep litter method on the ground? If not the deep litter method, how do dirt floors work? Any thoughts?
