Hey Sarah stay safe.
I have 3 mare herd and I'm the leader. Bindi would be the most expressionist, Frankie just looks for leadership and release and Ruby rue`the young one is very relax and abit hoe hum but when i ask for a task i have to follow through and finish with the rub other wise she would be all over me and we would have to go again, she dose have a short attention spand so short and sweet is the key with her for now. So to sum up "leadership" . I've never changed anything when they come in season Bindi has tried to change my "focus" once when there was some new horse's at the neighbours but i stuck to what ever we were doing to show "leadership" and continue on .They can still function in season don't make a big deal off it .Happy Horsey .
