Hey All! Found my way over here from frugalsquirrels, and been poking around all day. We're getting ready to make the plunge into some cluckers! Looking at starting out with 6-8 Buff Orph. hens. I've found a few tid bits on winter coops... But would like some clarification: I'm going to be building a coop. It's going to be a 4x8 coup plus a fenced in run. I am interested in knowing what precautions I should take for cold weather (USDA 4a Hardness). Insulation, Heat lamp, closable vents, open access to run, closable door to run, whatever else I'm not thinking of, ETC. Thanks!
