I tried a number of different things! I'm sorry to say we had to put the chick down. Along with not being able to walk, it could not eat on it's own and I fed it through a dropper. It was not growing. There were a number of things I tried. Poly-vi-sol infant vitamins, hard boiled egg for protein, tried treating for sprayed leg and curled toes by making a brace and chick boots. I had a hard time getting them to work and it just would roll over on it's side and couldn't move. I tried really hard and was very upset when we had to put it down. We just didn't think it was going to get any better. My other chicks were 3x the size and hatched the same day. I would try all the things above and make sure you leave it on shelf liner covered with paper towel. You can monitor it's poops and it will be able to move easier. Separate from other chicks because they will peck at it. Give it some time and see how it does.
