Possible fracture?

[Huckleberry]

My 9 month old Saanen, Flint, has managed to do something to his leg. When he walks he favors his right front leg, although he's bearing weight on it. When he steps down on it the hoof and leg shake like it's weak and sore and then it rolls out. Hard to explain, but his leg looks like it's slightly popping out on the outside around the same level as his dew claw, and his hoof rolls under and he ends up on his sidewall. He is bearing weight, but won't jump up or down from anything. Nothing is swollen or hot to the touch though, but something clearly is wrong. I don't know if it's a fracture or something else. His Hooves are trimmed and not the issue, it appears something is out of joint or fractured in his leg. I'll be taking him in first thing in the am, but should I wrap it in the mean time? It's pouring rain so he'll be snuggled up in their house and not out moving around.
