I have a 3-year-old colt, Hawken, who is always pretty nasty when he eats his grain. When I go to give him his grain, I go into his stall and use my elbow, body and voice to let him know that he can't get into my space and has to back off until I have poured his grain into his bucket. He still always tries to intimidate me, though, and pins his ears and tries to see if he can get away with anything. After I leave, even, he stands in his stall and kicks the walls and tries to bite his own butt for a few minutes, before settling down to quietly eat. He does better when he is outside of the stall, but he still gets nasty to anyone, horse or human, who tries to get near him while he is eating his grain, although if his stablemate ever comes close, he acts like a brat for a few seconds, and then settles down, just occasionally pinning his ears if his buddy makes a big move. He will allow him to eat out of the same bucket, though. I think that he is getting better, however, is there anything I can do to cure him, other then just wait to see if he matures out of it? He is not bad at all with his hay, except for a little bit of ear-pinning if you come up to him, but like the grain, he will settle down and get used to you there. He is a pretty laid-back horse, very willing and energetic, but has never really learned that he isn't on top of the horse pecking order, because the only horse he is ever with is his stablemate, mister bottom-of-the-line-at-all-times. I think that this might be part of the problem. He is also a nipper...not so much with me, as his main trainer, but especially with anyone he senses fear in or anyone new to him. I have tried many different ways to discourage his habit, starting with not allowing him in personal space, popping him under the chin with the lead rope, smacking his shoulder, etc, every time he tries to nip me. Whenever he is being worked, however, he is a sweetheart. Once again, he is better now then when he was younger, but still, I am really tired of having to warn everyone who comes to the barn "be careful of that friendly one, he likes to bite." I think that maybe I am just not consistent enough with my firmness of not allowing him into my space, or maybe it is because some of the other people in the barn aren't. Or the fact that he doesn't get worked as much as he would like. But does anyone have any other suggestions for his habits? Or is it all just a "young horse" thing?
