I noticed she was struggling to breathe yesterday. We live in Arizona. It’s very hot! Regularly over 110 degrees. I brought her inside to let her cool off. She got better and was pooping fine so I put her back out last night. This morning she wouldn’t stand in the coop and was struggling to breathe again. So she’s back inside, in the bathtub. She is standing. Her crop feels squishy, poop is liquid yellow. I don’t think she’s eaten anything today. No new hens or chicks, no new food. All other hens are good. They have full range of the side yard, well ventilated, no grass only a small apple tree. What’s wrong with her and how do I fix it? Thank you!
