Omg! A whole long post lost in cyber oblivion... Now, I am going to have to ask my question all over again... Forget it... I will just do it and if I don't like it later on, I will just deal with it.
how much roost space per bird?
I think most of the "experts" recommend 10" of roosting space per bird. That is what I am planning for in my coop-to-be!
