first off, great forum. we're very glad we found it. ok. we've just about finished a small coop for 2 hens (about all we can get away with) and it measures about 2.5' x 4.5' not including the run or the nesting boxes. I had originally read that apprx 2 sq ft per bird was acceptable but now im seein here that people recommend 4sq ft each...... I would hate to have to rebuild it if I dont have to, comments? secondly, is there a problem having chickens live on a wire floor so the droppings fall through? how do you keep it from getting too cold in the winter? (we're in rural Va, gets nippy in the winter) thanks for all the input!
