We finished the coop yesterday and put our 12 week old chicks in last night. This is their first day in the coop. I was told to leave them in the coop for a week so they would think of it as home and go back to it at night. I just checked on them and they are all panting. Not heavily but their mouths are open and they are panting. There are two vents up at the ceiling and two windows open, but no breeze right now. They have plenty of water. Will they be okay? I am worried if I let them out, we will not be able to round them up to get them back in tonight. They will be free range chickens.
