leg injury?

[Shadow920]

one of my cornish rocks has mysteriously started favoring one leg. she is only 7 weeks old and her food is cut back to meal a day which she shares with two other cornish rocks so she is not over weight like the breed is prone too being a meat chicken. there is no apparent injury, and as far as i can tee no broken bones. she has been in a cage on the floor, so she hasn't fallen from anywhere. does anyone have any ideas? and if so susgestions on how to fix it. she is very pitiful and seems to be in a lot of pain, whatever it is. please help.

Does she limp at all when she walks?

when she moves she hops on the one leg. she is not baring weight on the other leg at all.

Separate her from the other chicks so they don't hurt her more and leave food and water out. Look for injuries on other parts of her body near her leg. She might have injured her thigh and doesn't want to use her leg because of the pain. Could you please post a picture of her?
