chicken chiropractic adjustment?

[starryhen]

One of my young hens seems to have a dislocated hip (top of the femur). Her leg sticks out behind her. I managed to get it in once and she was standing weakly but it seems out again after a couple of weeks. I'm not sure how I did it the first time. Does anyone know where I should put the leg and where to apply pressure? I've also been treating her successfully for Mareks so that might be a complicating factor and cause. I hate to put her down because she was improving so nicely, but I'm considering it.
