To keep my chicken yard cleaner (they promptly turned it to dirt) shall I put the massive quanity if leaves my yard , and change out every so often. So far they seem to like it--but are afraid of the leave at first--the run is in high ground. Anyone see a problem with this instead of straw/mud/sand/or nothing. I got unlimited leaves, and assume that it will compost some poop. I assume that leaf mold and the like is fine for chickens as they used to hit the leaf piles when they were free-range. Free range here means death by fox/raccoon/or hawk.
