My first batch of "babies" are due a week from today....CANT WAIT:yiipchick. I have a brooder box built (thanks to someone here who posted a wonderful idea) and I plan to keep them in my basement. How long will I need to keep the heat lamp in there with them? I am also building a seperate coop/run for "grow up" chickens until they can be miggled with the adults. How long before they can be put out in the coop/run? I am in Ga and the weather here is pretty stable now. 50s at night, upper 60s, low 70s during the day. Thanks
