I really hate to sound sexist BUT (LOL) i have found it so much easier to train colts and stallions then mares and fillies. Why is this?? I wonder if its just coicendence at my farm or do other people see this. Maybe ive just been blessed with really smart stallions. We have only had black for a few weeks. He was not halter broke and is only 5 months old. In two short lessons he was almost completely halter broke. Yesterday i spent about 15 mins training him to stand for halter and hes almost got it already. My girls just dont learn this fast i have to say. When i trained Bitsy for halter this year I had to do it over and over and over. She did finally get it but it took much more time and repitition.
