Our two older chicks are now about 3 1/2 months old and are living outside in their coop. Recently the highs have been in the 90's and lows in the 60's here in north central FL and it's only going to get hotter. Their coop is designed with plenty of air circulation (basically, the coop inside is the same temperature as the outside air). The problem - every time we go out to visit our chickies during the day, they're panting and spreading out their wings and obviously too hot. We keep their water fresh, they have a decent amount of shade, and I've even tried putting bottles of ice water in their nesting box area to cool it off. The next step is to buy a box fan and set it up to try and suck hot air out of the coop but I don't know if that will be enough. Any suggestions? I'm worried that if they can't handle this weather (in May) that they might not make it through August.
