We have had some crazy weather this spring. Tuesday at 6am it was 34 degrees at my house. 36 hours later on Wednesday it's 86 degrees. When I got home from work today all of my chicks were in the coop. I leave the door open and they go in and out if their large safe pen all day long. They all had their wings hanging low and their mouths open. I changed their water and got them all out. They started acting nor al after that. They are almost 7 weeks old now. We're they too hot??
