Yes we could be rightfully worried. Even though it takes some time out of my day to make sure my birds are ok, I do it because I didn't want to lose any of them. I believe I can attribute my recent pullet's death to trying to pass an egg while it was hot, and of course the nest box didn't make it any cooler for her. I spray their feet and get water in between their feathers. I wet their run down so if they try dust bathing they end up mud bathing, and they could wallow in a nice cool hole. I also give them some frozen treats every now and then such as yogurt or frozen sprouted wheat berries.
