I lost one of my girls today to what I believe is this terrible summer heat and stress. It has been around 100 degrees every day for awhile now. This afternoon my hubby mowed the lawn around the coop and run. I think a combination of the heat and the stress of the mower was more than she could handle. I found her several hours later. It was a horrible feeling picking her up. So please people, do what you can to keep them cool til the summer heat fades.
