Hi all I'm in the planning stages.. I'd like to have a dozen hens. I have the opportunity to get a 4x6x66" chicken coop with 3 nesting boxes. I like it because it has a people-sized door I can get into, for one thing. I would also be able to have as large a run as I like, and the hens would be able to free range during the day. So in this scenario, what do you think? Thanks!
