I'm sure everyone's tired of newbie's asking questions about coop winterizing, but there are SOOOOO many conflicting answers out there. I am raising my first chicken babies, and they are doing great. I have 8 Silkies(I think 6 are roosters, NO JOKE) but oh well. My concerns are regarding insulation and heat lights. I live in Michigan, where it usually hovers around 0 at night, and is frequently windy. My coop contains a covered outdoor run, and a hen house. The hen house is about 4' X 4', and the roof peaks at probabaly 4' tall. Not big, but neither are Silkies. I do have a light socket in the ceiling of both coop and run, but I don't know if I should put a bulb in them for heating, or will I cook my babies in their hen house at night becouse the ceiling is so low. Should I just use sheet insulation in the house (and of course cover over that with more plywood) Should I insulate and heat with a bulb? what wattage should I use? How about outside? Would my babies benefit from a heat lamp when they go out, or is that totally unnecessary? It's all very confusing, and this is a time that I do not want to learn from my mistakes! I'm seriousluy thinking about buying some chicken diapers, kicking my husband out of his side of the bed, and moving the chickens in for the winter : ) Thank you all in advance for answering another coop question!
