Hi, all. After lurking for awhile and learning TONS, I've finally joined the forum! I haven't had chickens in ages and am pretty excited about the EE chicks I've ordered (I hope to get some Ameraucanas later as well). DH and I are building a coop (this forum has been a goldmine of help with the design) and we're trying to decide whether it should be insulated. Our neighbours' coops aren't insulated and their hens seem fine, but I want to make sure our girls are comfortable, not just survivable. Winters here range on average from -5 to +5 Celcius (23 to 41 Fahrenheit) and the coldest it gets is about -25C (or -13F) overnight occasionally. Summer temperatures range from 15 to 30 C (59 to 86 F). Our coop will be 8x8, raised 32" off the ground (the height at which my 6'3" DH can scrape the floor with a shovel without bending his lower back). The interior walls will be just under 4' high and the peak of the roof will be another 4' above that (it's a steep pitch as we get a lot of snow here). The high roof will be good for ventilation but maybe not so good for heat retention. The run area, including underneath the chicken house, will be 8' x 20' and fully roofed (again because of the deep snow). I plan to have somewhere between 12 to 20 chickens, and the Ameraucanas are known to be cold-hardy... Sorry to be so long winded. Basically my question is: should we insulate it? Thanks!
