ok, so its really hot here in the summer, so my chickens' "coop" is a big dog run with a roof. It has roosting areas inside it. And they hate it. there is a nice low tree in the run/yard and that is where nearly all of them sleep. So, my question is, I've noticed that egg production is very low. I'm not sure if its beacuse of the heat or because they are sleeping in the tree and have made wallows under it for daytime, and don't have boxes out there. They never go into the coop, even though its ventilated and shaded.
