Don't accept her into your herd until she is showing acceptable behavior. I hope this makes sense, its somewhat of a mouthful, I apologize.
I don't bring those people to "see" her (and if I do and those are complete strangers she just stay away from everyone and don't socialize).
Those are my parents who go in field every single day (and mom feeds in morning because I work) to help me out with manure and such. So no even talking between us in field, or nervousness, or heart rate increase, and they usually ignore her for the most part (when you clean the manure you don't care much about everything else anyway). If I stand between her and my parents she behaves, because I can drive her back any moment and she knows it (I don't even need the whip for that). The problem is if I don't pay attention and not in between (say behind her talking to my other horse) it's when she may try to attack. Now I'm just trying to be right next to her all the time to stop her and they stay away - this is temporal solution kinda. I'd think she considers them as part of the herd lower order then her, but then I'd expect her to behave the same if I'm not around. But it's obviously not a case, and that's what bugs me.
BTW she had lots of horsey communication (unlike Jemma). She was running wild in big herd before I got her and then in field with 5 horses.
