I live in North Idaho, so we get all four seasons here, and with it being summer, we are getting up into the 90's and even 100's. Most of my run is shaded by a tree, and they can also go under the coop for more shade, but it still gets pretty warm in there! On top of the heat, I have all different breeds, including a Brahma, Wyandotte, Australorp (black), Orpingtons, Olive Egger, ISA Brown, and a Marans. I am especially worried about my Brahma, with all her beautiful (but warm) feathers. I of course refill their water every morning, and, starting tomorrow, I will put ice in it, but it still doesn't feel like enough. None of my hens are acting off, so I think they are ok as of now, but I want to prevent any sickness (or even death). What do you guys do to keep your flock cool in the summer? Any tips and tricks is appreciated!
