Hen crippled all of a sudden. IDK why?

I've never had a hen go lame on me. She is about 6 mo. old and laying good. She is a mixed breed. She was fine jumping around and running and all of a sudden she is walking on the "knee part" of her legs not using her feet. She just hobbles around. I have her seperated for 2 weeks hoping she'll snap out of it but nothing. She's eating and drinking and still laying. I just wanted to know if anyone else had this problem. I tried to feel for broken bones but I don't feel anything odd.

Check to see if her legs seem to be paralyzed. It could be Marek's. They don't always present with the classic one leg sticking out position.

I'll look into that. None of my other birds have any symptoms of anything. They are all very healthy. I haven't brought any new birds in for over a year. ???? Poor little girl.
