I have not started raising chickens yet, but am planning to start in the spring. I have been spending the winter reading up on raising chickens and coop designs. I have recently read a knowledgable booklet on open air coop design and the benefits that it has over closed coops. I live in an area with relatively mild winters (although it can get into the single digits on occassion). My question is, how many of you have open coop designs and/or I am seeking opinions on such. I would have a large relatively predator proof run to go along with it. I am looking at fewer than 10 chickens as pets and for eggs. Thank you
