I have a blue wyandotte chick. It has been healthy since I got it. Just noticed she has been sitting down a lot. So I made her move and one leg looks like she can't keep it under control? It doesn't look broken. Any suggestion? Could it be something she's lacking? She's with other chicks her size so I know she was not jumped on. She also eats and does move around but as soon as she get there she flops down to eat. Will not scratch at all. Any advise or help I would love. She's a beautiful pullet! Thanks Yancy
