Helping a freind convert a large shed into a coup. The plan is to make 2/3 of it into a screened in Run and then the last 1/3 into where the hens nest. I was thinking I would leave the bottom part of the nest open for the run as well. The sheds about 7 feet tall questions I have is. 1. How large should I make the hen house , I was thinking 3 feet with 2 roosting bars? 2. Can Iput a Hard wire floor in the Hen house so most droppings will fall onto coop dirt floor below or do you suggest a solid floor. where I live I didn't get freezing temperatures so I don't think its needed to keep warm. 3. Should Nest box be off the chicken house or ok to be in run area.
