I have had my 3 hens, 1 rooster since Dec. Came from San Diego, Ca. to Kingman AZ. Now its 95 degrees here and they quit laying, well, 2 eggs in 2 weeks! I put in another window, put in a fan, went to crocks of water along with their self-waterer (4 gal bucket with chicken nipples). They have lots of shade too. Still no eggs except those 2. I think they are just not happy in this heat. They sure loved the snow in Janurary though.
