It's a 100 degrees in the coop and would be a lot warmer if I had the door to outside open. I'm putting ice in the water every hour and I brought the 12 week old chicks back in the kitchen of the house. They were panting like crazy and hanging their wings. The 5 little ones are handling the heat just fine. I have no shade in the run, so I can't put the mister out there. I'm keeping the door closed. We are not finished with the run, we need to shade a section. Tomorrow is suppose to be even hotter. It's 98 outside and muggy. I can't believe how good the 3 twelve week olds are being. They are resting in the kitchen under the table. I've never heard them be so quiet. They must be super happy. They were in the kitchen earlier today. Anyone else dealing with this heat? I'd never thought I'd be this worried over my chickens.
