I am just getting started (no chickens yet). I have a homemade coop through freecycle and I wanted to ask if it was sufficient, and for how many birds. Here's the basic idea: Coop measures 37" by 30" (footprint). As you see the roof is sloped, height at the top is 39", height at the lowest point is 26". There are 3 nest boxes mounted inside the coop, against the tallest wall, raised above the floor so that there is 14" of head space under the boxes: The interior is lined with (deteriorating) foam which I am removing - I'm not sure insulation is necessary. My plan is to stick this coop inside a 8x10 dog kennel with some sort of roof to prevent hawks from picking them off. I also think I will raising the coop up more with another round of cinder blocks so they can walk under it for more room and shade. So any advice - how many birds can I put in this coop? I'm not interested in bantams, and would appreciate any suggestions on breed - my main concerns are getting a breed that is cold hardy (I'm in MA zone 5b/6a) and that is productive for as many years as possible. Thank you for any suggestions. I'm sure I will be back with more questions.
