I have a 10 week old Silkie/Brown leghorn mix that suddenly lose the use of one leg yesterday. I have her in the house because I thought she might have injured it. But when I was holding her, I started to feel some creepy crawlies on me like on my neck line area. I can't see anything on her but I can feel them on me. She is the only one in my flock that is having a problem walking. She is alert, active, eating and drinking well, she just lost the use of her leg. It seems mostly affected from the hock down. I didn't feel any obvious breaks or anything like that. She was fine Friday morning and when I came home from work, she lost the use of her left leg. Her toes are folding close together. I am suspecting the right is either starting to become affected or she is walking on the hock on that leg because it is easier for her to get around that way. I supplement my guys daily with polyvisol and they are still on chick starter with treats. Her scales look fine but I am going to look over the others to be sure. Any ideas???
