possible to change horses attitude to other horses?

[showpony]

So have my chap couple of mths and he is a total humans horse, super affectionate with people but seems to have an utter dislike for other horses
where he is stabled there are rs horses in a coral just outside his box. Today he managed to escape as kick bolt wasn't on and tried to double barrell one of the rs horses ( a heavy set 17.2!) . in the commotion one of the smaller ponies went into his stable and he reacted by literally grabbing onto the ponies neck! when put out in field with my mare last week he kicked out at her at gate and there was a bit of a scuffle. He is well 9 from today, is there anyway I can try to make him more accepting of other horses?

My lad is a terrible bully, now I chase him off if I catch him bullying the others, today he wouldn't let the others share the hay bale, so I chased him off it and wouldn't let him back till he stood still and I told him he could go back, prior to that when I had a barn, I would send him out and only let him back in when I said he could, it's early days, but seems to be working. You should be the boss

Today happened in a split second, and it was a matter of get pony out of stable and get him locked in. Re incident with my mare was about 20 metres from gate before things kicked off. He is very submissive with humans just not horses so just wondering if there is anything I can be doing ground work wise to make him more accepting of other horses?

When my bully boy was threatening the others, I would stand between them, growl at him and make a fuss of his target, I realise your situation is different, but I would put him in a dually halter and let him meet other horses over a fence, if he is aggressive, give a firm tug, a loud no then try again, dually halters are really good when used properly, good luck

I think the incident today was actually fair enough, not really acceptable behaviour but totally understandable, he may feel threatened by the others being loose just outside his box, he could be worrying they will get his hay and the need to defend it and his space, he was correct as once out of his box another pony went in and tried to take over.
Could he move to somewhere quieter, away from the coral, he really may be struggling to cope and could get worse by being forced to remain constantly on guard, this may be in part why he is aggressive when in the field, rather than try and change him change his situation and see if that helps. Not all horses like to be in really close proximity to other horses, some need space and privacy, just like we do, otherwise they strike out in any way they can.

It often takes a long time for a horse to have a settled relationship with others. If yours is like this a riding school where the other horses are always changing may be a stressful environment for him. If he is always turned out with the same horses, while he is likely to fight for his place in the pecking order at first, once he is settled in a stable group things will no doubt quieten down.
