I have 15 New Hampshire Chicks that are about 3 weeks old. Being a first time mom I'm trying to be as cautious and observant as possible. All of the chicks seem healthy and happy but i was wondering if they could go out to their coop yet? Its currently 100 outside and 93 in the coop. I have both windows open and i have a box fan going. I tried putting them out there for about 45 minutes but a few of them (mostly the big girls) started panting and laying down with their wings spread out. Normal? Not normal? I plan on improving my air flow in the coop within the next few days but its only the start of the heat to come. Keep them inside for a few more weeks? Or no? Help!
