That you all for your replies. My coop does have very good ventilation, and it's always nice and shady in there. It's going to be over 90 degrees today, so I put out some extra water. I put some vitamins in one of the waterers. I'm going to put out a big plastic bottle filled with ice for them...
We're going through a heatwave where I live right now, and my chickens are definitely not happy. They have lots of shade and water, but I want to do more for them. What are some good ways to keep them cool?
