Maybe a mister hose? Another poster said they use a pistol style sprayer on low/mist. Not enough to make mud but a damp area.Need some advice, my chickens have been walking around panting in the heat for the last couple weeks. Free range, shade is available, a cool area in the grass, they have cool water available too. Is there anything else I should be doing? it is about 103 out...
Other people have used shallow pools. (My birds said no way) Some also put out frozen water jugs for the birds to stand or lay on.
Maybe put a fan out somewhere they could stand in the breeze.
I would say as long as you're giving them options to stay cool that's the best you can do. We've been lucky here that it's so humid, overnight droplets have been collecting. I have damp dirt areas that the birds are sprawled out in during the day.
