Hi all. Ok I am ready to install the roost. I have read here that 10-12 inches is optimum per bird but I am wondering how much I can alter this number? I have 8" per bird that I can convert easily to roost space. I would like to do just eight inches per bird because it will leave more floor space if I do. I have read while surfing that six inches is adequate but I sorta doubt that number. Would you go for eight inches per bird or would you lose floor space and add room on the roost? This is a small coop of only 32 sq ft for six chickens but I want it available for up to eight hens if possible. I think each area taken up with roost will reduce the usable sq ft of the coop. If it matters the birds range in size from the largest being a Brahma to the smallest being a faverolle. Thanks again.
