I don't know what happened, I just now noticed it, he's almost 6 weeks old and I don't think he was limping b/f he sat on my lap and then got spooked at something, then jumped up and ran off slailing around and falling. Can a leg swell that fast? Now he's limping and won't sit with it under him. THey graze all day, do they still need brewers yeast? I'm just wondering when this happened... geez, poor thing, I feel so bad... what do i do? jennifer
