I've only witnessed very minor skirmishes between my clowns, none of which has yet involved the alpha so maybe this is unusual. Mine arent that old yet, my oldest 3 are around 2-3 yrs. Out of the group of the oldest 3 the smaller two have fought a little recently. I dont know if they are fighting for the second position or what. Or maybe since they are still younger, its something like teenage fighting, IDK. But the biggest of the bunch just kind of hangs out and doesnt do a whole lot, never has been in any fights I have seen.
