Hi, I never raised baby chicks. Here's the story - one of my 2 remaining silkies died last week. My one remaining silkie was broody so I bought her 2 chicks from the feed store and put them under her 2 nights ago. She accepted them instantly. Now I'm worried about the heat wave coming. The coop is small (3 x 3 ft) located in complete shade of holly tree and stockade fence. The southwest wall and roof are insulated. Both side walls are more than 1/2 open to air and I have a fan on the outside to blow a little breeze through the coop. The pop door stays open as I have a completely secured run that is also covered and mostly shaded. Is there anything else I can resonably do? (I am not installing an A/C unit). I have tried misters in the past but I find they clog up quickly and make a muddy mess. I'm afraid of drowning chicks if I put out a pan of cool water for them to wade in.
