Hey everyone! We have an outdoor coop and chicks that will be 6 weeks on Saturday. Some have a LOT of feathers and one has some spots not filled in. Right now they’re inside with no heat lamp and the house is set at 68. We live near Madison, Wisconsin and the days are in the 40/50s but the nights are still pretty chilly. The coop is staying in the 50/60s. When do you think we’d be ok to put them out there all night with a light and then without a light?
