Help! When I let my 6 girls out today. One of them was walking really slow and staying low to the ground. Her head was lopsided and she wasn’t making any noise. She drank water and ate a little . She couldn’t keep up with the others, but finally made it to their bath spot. At dusk I went to close the pen and she was laying on the ground instead of the roost. I stroked her and she didn’t seem like she was in pain, no obvious wounds. What should I do? I’m a first timer, she is about 18 months old. I have never medicated them and they free range 4 or more hours daily. I didnt get a chance to see poop, her feathers were ruffled on one side.
