Can my 14 week old bantam (3) chicks stay in their hen house during 30 degree night time lows without a light or heat source? Their house is a small A-frame with an open front. It is open into a very secure run, so no predators can easily get them. I just put a light out in their coop to try to keep the temp a little warmer but noticed the chicks came out and began to run around in the coop. I guess they think it is morning. I am afraid the predators will see them, try very hard to get into the coop during the night and they just may succeed. Thank you for any pointers you can give....Florida does not have many nights like this!
