My chick around two months seems to be having a leg issue. Sometimes one leg seems to be more forward than the other when she is laying down. If on a slippery surface one leg slips forward. Can still walk around fine but typically lays down after a short time. Always kind of a weak chick, some balance issues, runt, a little slow to feather, but always got around and got enough to eat. What should I do? I have been trying to give her more fruits and veggies, seems like it might be a vitamin issue? I have heard this can happen when they grow up on a slippery surface too, but her cage has towels and woodchips. I've been gone for two weeks so its possible I missed something happening she wasn't laying down so much before..
