Help please. Ok ladies and gents.. I have a 5x5 coop and it's about 6 feet tall. My chickens & ducks are about 3 weeks old. I'm wanting to move them outside with a heat lamp. The low temp is going to be 20-25 and the highs this week are going to be 40-50. I'm not looking to kill the little ladies. Do u guys think it possible to make the move to the coop with a heat lamp?
