Well, They used to walk nicely.

I've found that goats can get pretty frisky this time of year through spring. Maybe it's cabin fever, or maybe it's the lengthening of the days, but even when we had just Cuzco, sometime in late January, early February he would start behaving very differently and would start challenging people and horses and attacking trees. Young goats are experiencing the beginning of their spring growth spurts and changes are probably taking place in your herd dynamics which may be hard to pinpoint other than fighting among the ranks. Pregnant mamas may be jockeying for better positions in the herd (or at least demanding more respect from their superiors) before their kids are born.

Since old alliances may be changing, you could try switching up the groups that walk together and see if that helps. Unless they're fighting so seriously that they refuse to walk with you at all, then you can always let them duke it out. Just make sure to bring a spray bottle or stick to keep them from fighting near you or other people. You don't want to get in the middle of a goat fight, but sometimes they need to get those goatly arguments out of their systems and it's ok to let them do it if they're not endangering anyone.
