Ok so I too have caught the backyard chicken bug!! I just finished my first coop and would like input as to what you all might think. Another thing i was wondering...in the summer here I am not too worried about the chickens but what about in the winter? It gets to single digits here in the winter. Do I need to button up the coop tight and block off any openings ( except the pop door) or can they take the cold. I wouldn't want to be out in that cold of temps! My coop is insulated in the walls.....Any advice would be appreciated! Thanks!
