I needed this article! We've been having excessive heat warnings every day for a couple of weeks now. My egg production dropped, and my ladies were stressing from the heat. So, I've been taking action to help them cool down a little. I have plastic drinkers that I fill halfway with water and freeze overnight. In the morning, I fill one of them the rest of the way and bring one out first thing in the morning. Later on in the morning, I bring out the other drinker and set it in the other end of the run where the shade is. Then I hose down the coop and put a gentle spray over the run. I started making ice cakes with their treats and I give them those in the late afternoon. They've been responding to the cooling and are laying their eggs normally again.
