I need help! I have 4 2 year old hens that I've only had for a few months. Their previous owner had them in an air conditioned coop. Today was our first (of many I know) 100+ degree days. My ladies are not doing well. They are all panting, at least 2 of them have had VERY WATERY diarrhea, and they just generally look hot. I have a fan in their run, put a frozen water bottle in there today and can move that into their coop before they go into roost tonight. I need advice! What do I do? And air conditioning their coop is not an option . I live in central California.
