I have a wether that a vet refused to disbud at 10 days, because he said the horns were already too big for his iron (he did another kid that was younger at that time, and did a perfect job). I really wish I had been able to talk him into it, because those horns have been a headache for me ever since! This goat doesn't butt people, but everything else is fair game - trees, fenceposts, walls, stall doors; the only thing he doesn't butt is my mini mule, but he's terrified of her! I lost a doe a few years ago under mysterious circumstances, and I have wondered ever since whether this guy might have killed her. I have seen him duck down and use his horns to snag the legs of the other goats; I've seen them sore after this trick, but no broken legs so far. I had to take the collars off of the other goats after he nearly strangled one (it was deliberate; I saw him do it). The only good thing about those horns is they keep unwanted visitors out of the pasture - I know he doesn't butt people, but nobody else does!
