Hi everyone, I went out to the coop today to let everyone outside and I noticed that my laying red, ginger, was on laying on the ground upright. I opened the door and she did not move (very unusual for her), so I went over to her and tried to stand her up and when I did I noticed she was holding one leg in the air. She can stand, but she can't walk and so I brought her into my house in a crate with bedding and food. I fed her water with a medicine syringe. I can't seem to find any bulges or anything unusual with her leg other than she won't put it down. What is wrong and it there anything I can do for her?
