It's already in the 90s in south Texas and it's only the end of May/early June. How do I keep the girls cool? They have shade from trees, and some from the shadow of the garage. Will they need a trap or umbrella type covering? I've tired introducing a dish pan of water to soak their feet in, but they looked at me like I was nuts. I just put a fan in the coop too. It's up high, in a window. What else can I do. The poor girls are already panting.
