We are talking about moving our 7 week old chicks outside, making them their own coop until they are big enough to move in with the others. The temperature outside is everywhere from 40 to 70 in the morning. At night it gets down to the 30s and 20s. Are these temperatures too cold? If I can move them out, what are some ways I can make them feel comfortable? Gould we wait until their older? One last question; what is the coldest temp I can let them outside in? Thank you all!!
