My JG roo Beretta is limping on only one leg and not putting any weight on his other.As you can see, he still crows, eats, drinks, and tries to wrestle with the ladies like normal. I see no bumbles, swelling, redness, excessive heat or feel any breaks or dislocations. He is just at a year old and being a JG is obviously still growing. Are these "growing pains" or something else??
