I brought home a young chick- only a few days old. I don't think it's spraddle leg since its leg isn't laying flat out. He is just sitting. He will put weight on the one leg if I'm holding him up but he didn't like it when I gently stretched his other leg out. He is eating and drinking, thankfully. What can I do to get him on his way to walking? I attached a photo of the little one.
