Help with this sick Chicken Please

[RIRgavin]

I have a Road Island Red Chicken who is about 7 months old and will not walk. I gave her a bath with no change. She has never laid an egg. DO you know what could be wrong with her?

Is this something she just started recently or has she always been like this? How long have you had her? She may have an injury to one of her legs that's keeping her from putting weight on it.
