We live in a desert environment, so summers can be brutal! I have their enclosure, with a coop inside, covered partially with a cotton blanket that I soak regularly to keep the temperature down. It dries very quickly. I also provide clean water trays for them to stand in. I still see some panting with the Orpingtons, in particular. Today I’m trying a portable misting system near them to keep the temperatures down. Anyone else have any suggestions? All seem healthy so far. They are 4 months old now. 1 rooster, 5 hens.
