Yesterday I moved 22 of my 8 week old chicken to a large coop house from a smaller above the ground hen house. This was the first time any of them had been on the ground and had so much space. They all seemed happy, dirt bathing and running around. There were some bullies but nothing major that I saw.
This morning I went out and one of them was laying on the ground not moving around. She couldn't stand. I have her in isolation now. I felt for broken bones but didn't feel anything. No scabs on her feet. She can move her legs and curl her toes. She ate and drank when I placed food/water in front of her.
I went back out a few minutes ago and her nose had blood spots. She had moved around some but was still laying with her legs to one side.
Could one of the bullies hurt her or could it be an illness? Any ideas are greatly appreciated.
