Ok....now that you've said that, I am going to 'offer' some advice so that you can be effective when you do choose to have this 'meeting' with her..
1. When she offers you a 10....you come back and give her a twenty....
2. Do it like you mean it.....if she offers you any aggression like kicking, front footing, rearing near or even worse over you, biting, charging and you mean to whack her for it.....do it like you mean it...
A bit tongue in cheek, but somewhat applicable.
Also, little things count. Does she ever get fussy being led? Does she cooperate getting her hooves cleaned? If you stop her on a lead line, does she stop? Or does she kind of stop? We tend to think these are little things, but horses look at them and think, "The King is getting old. Maybe it is time to replace him..." You may need to get in touch with your inner King Henry VIII!
I'm not a trainer. I'm not a pro. I don't compete in anything and my horses - all THREE of them - are works in progress. So take this with a big steaming cup of FWIW
The best time to deal with a kicker is before they kick. Find a small thing. Just lead the horse somewhere, stop them, and then start insisting they don't fidget. Fidgeting means going backwards or disengaging until they get the idea that moving around is unacceptable. Come armed. If a fight develops, be prepared to win. You have the advantage of picking the time and place, so pick it well.
Horses don't start showing dominance by kicking out. Neither should you. Like them, start with little things. Start them when you've thought it out, and have a plan A, plan B, and plan C on how to win.
If the horse starts to 'lose', it may back down. Or it may decide you've brought a fist to a knife fight. If it does that, you need to be ready with a gun. That is why you need to think things thru in advance, and pick a time and place where you are prepared to do what it takes to win.
“If any of you wanted to build a tower, wouldn’t he first sit down and work out the cost of it, to see if he can afford to finish it? Otherwise, when he has laid the foundation and found himself unable to complete the building, everyone who sees it will begin to jeer at him, saying, ‘This is the man who started to build a tower but couldn’t finish it!’
Or, suppose there is a king who is going to war with another king, doesn’t he sit down first and consider whether he can engage the twenty thousand of the other king with his own ten thousand? And if he decides he can’t, then, while the other king is still a long way off, he sends messengers to him to ask for conditions of peace." - Jesus Christ
