I found my 9 month old PBR hen sitting outside in the yard when I went out to shut up the coop tonight. So, I picked her up and brought her in the house to see if she was ok. Her crop was empty, but she seemed hungry so I fed her some scrambled egg and gave her some water. She was very hungry and I noticed while she was eating that she was missing the target a lot. A light shined in her eyes shows no pupil constriction at all. I put her in a bin in the laundry room and she was resting well, but I checked on her a few minutes ago and she is lying down and is having labored breathing. She does not appear eggbound and she is not showing any signs of infection. Any idea how to help her or what is wrong with her?
