One of my 5-week-old guineas seems to have have either broken or dislocated her leg. Her right hock joint is swollen, and she holds her leg at a slight angle. She seems to have a least some control of her leg, and still walks/runs/jumps. (But she is very skittish, so, I think she'd run away no matter what.) Should I even try to help her, or just put her down?
