Here's what I have: 1. Climate - central Florida, can get very hot and humid a few months out of the year. 2. Zoning allows livestock, as long as it is not a nuisance. 3. I want to have a roo to incubate my own chicks Need suggestions on how to build a coop that is pitch dark and well ventilated at the same time. Short of installing an air conditioning unit for the chicks - you think this could be accomplished? And, oh, they will be free-ranging in a decent size fenced-in area during the day. So the coop need not to be large.
