When I had chickens before (probably around 1989 or 90) I never did anything special in the heat. I think we may have lost a couple of meat birds but only the ones with funky legs that couldn't get around so well. I don't remember ever losing a layer to heat back then. I wonder why it's so different now. We haven't had any trouble this summer but our chickens are all still chicks at around 10 weeks now. I'm sure next year will be different so I'll at least put fans in the coop. I hope everyone's chickens cope. We're finally out of the 90s as of today but I know that's nothing compared to the numbers in the deep south. And I'm sure those nasty 90s will be back.
