We have been doing great with the heat. I let the girls out to run around and I water down the cage run every day. we are getting 8 eggs out of 11 hens. Well my sil had a false labor run and I was gone all day Sunday and until late afternoon Monday. My husband watered the chickens but did not spray them down (I did not ask him to though) There were two dead chickens. One of the pullets (brown leghorn) and one of my 1 yr old barred rocks. One was in the run and one was inside the coop. I am assuming it was the heat since we hit 109 yest. I am worried cause it will be 111 today. I will spray them down good several times.
