My ladies are 20 weeks old. They are free range and last week a hawk got one of them. So when we are at work they now go into an enclosed pen then when we come home they go free until night time. Today one of them were trying so desperately to get out, she was panting and her wings stuck out a little and she was squawking up a storm. I thought maybe it was because she was hot. But dont think so. As soon as I let just her out she wanted to go into a corner and she started scratching away and acting maybe stressed out, I'm not sure, after a while I let the others out and they were fine but she went and found a place to lay down that was dark and under our porch. After about 30 mins she came out drank alot of water and was normal. hmmmm any suggestions? I do know when I approach them to pick them up or pet them they squat and spread out their wings a little.
