Agree with the above posters. If they're aggressive like that, they probably shouldn't be in turnout with other horses anyway, and if my BM tried to do that to my horse, I would be honest and tell her that. If they (the owner or BM) refused to put the horse into private turnout, then I would request private turnout for my own horse, request that he be moved, or possibly look for a new place to board.
I hate being a picky boarder, but my gut says "no" on this one. At a previous barn where I boarded, a hind-shoe-wearing kicker nailed a horse while we were on a trail ride and DID fracture the horse's shoulder. I was there, it sounded like a gunshot-- it was awful. (Horse recovered, but I'm not sure to what degree of usefulness.)

I would put your foot down and say no, if nothing can be done then I would consider moving to a different barn, but this is coming from somebody who is dealing with fresh wounds on my horse from her pasture mate that has hind shoes. Not fun for myself or for my mare. I was seriously worried for a few days that she may have broken something, but she appears to just be suffering from a lot of swelling and bruising. I have seen a horse get kicked and break its pelvis, it was awful and the horse had to be put down.

I would definitely say no way unless I had personally seen the horse kicking and judged each occurance as self defense and unlikely to happen with my horse. One of mine got kicked by a known kicker - fortunately just some time and daily injury care and he was fine - and I later saw that horse running backwards and double barrel kicking at another horse who was quick enough to get out of the way and smart enough to keep going until the kicker stopped moving.
some horses are just nasty in turnout. I had a gelding who would beat up one particular field mate but no one else. I boarded another whom I swear spent half of his life in reverse- he sought to bully others. I kicked him out.
Not every kicker is being harassed, not every field is crowded. some horses, like some people, are jerks.
And those horses are likely better in solo turnout.
Some horses do fine in turnout, others not so much. Our barn watches closely the interaction between horses when turned out to determine if it's going to be a good match or not. DD's mare is in a pen with two other mares and a gelding. The gelding does not tolerate other geldings. We have one horse who needs individual turnout, so he has his own pen.
FWIW, our barn doesn't put restrictions on back shoes for turnout - about half of our horses live outside anyhow. Given that they all have different jobs and some need shoes to stay sound, that wouldn't go over at all. The one time a horse was injured by being kicked, the kicker had no shoes.
My barn won't turn out horses with hind shoes in groups, just alone. The paddocks are set up to accommodate this. As the owner of a non-aggressive horse, who has always adored being out with his buddies, who absolutely needs hind shoes to stay sound, this is frustrating - but I understand that the BO and the other boarders are unwilling to take the risk. Perhaps this particular horse needs to be out alone or with just one buddy that he gets along well with?
A confirmed kicker in a boarding situation should be turned out alone. Doesn't matter if the horse has hind shoes or not.
I have a mare that can be a kicker, depending on who she goes out with. Without hind shoes, she injured one of my other mares bad enough that we thought she had broken the top of the mare's humerus. Luckily, nothing broken and after 10 days of stall rest, all was well. I can turn her out with a different mare with no kicking. However, when she is leased out (as she is now), I tell them she must have individual turn out. Not worth the risk.
I take it on a case-by-case basis. I have a mare with back shoes that can go out with any horse, even weanlings without a problem. She gets along with everyone and just does not kick in turn out.
Despite recently telling a trainer who had my horse for a week of training that I was NOT comfortable with him being turned out with a certain known kicker with hinds (who has done damage to others before by way of double-barreling), my horse was turned out anyway with said horse. I was told the horse was "mean" to mine, and mine was moved within 30 minutes or so.
Fast forward - my horse ends up spending a full week at the clinic for internal bleeding from "trauma" that the vet was 99% sure was from a kick. of course I can't really prove it, so the bills are mine, but I will NEVER allow my horses anywhere near a kicker again.
