We had a heat wave recently and my chickens ate mostly cool treats. But I would say on a normal day my lot go over the 10% treats anyway and all are doing good.
I've been putting out litter boxes with cool water on most warm days but they refuse to use them so far (109 again today and the nitwits still won't try it). I even tried to place my friendliest hens in them but they flew out and haven't returned.
I did put frozen bottles of water out there today and more in small kitty litter box. Hoping they give them a shot in this heat wave. I dote on them daily and they are still so suspicious of everything I do for them, lolA friend of mine once mentioned freezing bottles of water and putting a sock over them, apparently his chickens would cuddle them to help cool down! Obviously don't put them in the sun haha
Well all we need to do is provide and leave it up to them if they want to use it or not. As long as they have lots of shade and lots of access to water they should be fine. Pouring some water on the ground too can cool down the ground temperature. You can hang sheets over fencing to provide even more shade. Spraying the coops with water and leaving iced water in the coop can help bring temperature inside the coop down. I had a broody sitting on eggs during one of the heatwaves here trying to keep her cool was not fun!
Mine have been doing that too
