I have four sex links that were hatched 3/20 they are now just over two weeks. I have a small outdoor coop with small run I set up the coop with the ecoglow and food water roostin bar and sealed off nextong boxes. When can I just leave them out in the coop? I was going to bring them back on the garage at night wih the ecoglow in the glavanized cage until the are ready to be left outdoors. I'm in Cali, mornings are still cold a times as low as 39
