I have 25 birds on the way in May and am getting started on my coop and run. The coop will be 7X16 and the run will be 16X16, with occasional access to about two fenced acres, assuming our bloodhound can make friends. I'm pretty set on how things will look, but I'm not sure if I should insulate the coop or just put in a heat lamp when it's very cold. I live in Spokane, Washington (zone 5). Also, will 6 nesting boxes be ok? What size waterer and feeder is needed? Any other advice would be appreciated as I'm new to all of this. PS, I think this site is great!
