I am about to build the roost for my chick coop and I am planning a flat roost will several "polls". I have about 10'X 4.5" to work with. Is that enough space for 42 chickens? I can't remember the spacing for the chickens (I think it is 10" right to left) but the distance between polls, I don't remember. I know they should be far enough apart so the chickens won't peck at each other. Your help would be great appreciated. I am going to tackle the roost tomorrow (I hope).
