I did all I could think of to help keep my chickens cool today. They are calling for a day with temps of 99 in the shade. Heat index of 106. I put ice, and electrolites, in their water, laid out frozen 2 liter bottles, bags of ice cubes and freeze packs. About 5 in all. I even took my daughters snow sled, put in their run and filled it with approx 2 in. of cold water. I have to work today and I kow I'll be nervous about them the whole time. I'm lucky enough to be able to come home during the worst part of the day. I know the australorp seems to take the heat the worse. I can't think of anything else to do. Please send good vibes out for my girls today.
