I just finished reading "Keep Chickens" by Barbara Kilarski. Great book. But in it she often refers to using chopped straw on the floor of the coop. That sounds like a great idea (maybe it won't get as matted as regular straw) but I have no idea where to get it. I asked at the Co-Op where I get my straw bales and they had no clue. Also, I started using cedar shavings over a month ago in the henhouse and nesting boxes before I read that it was dangerous to hens. I really like using the shavings. Have I done them damage? And am I to assume correctly that pine shavings are OK?
