In general, is it easier to join up with a gelding than a mare? I have three horses, two geldings and a mare. I was working with them today and did the join up process with the two geldings. One joined up very quickly, the other took more time but it happened. With my mare, it never happened. I finally just called it off with her and will try at another time. It was like she just got more and more upset and really frantic.
