I'm at the end of my rope right now. I cannot catch my mare, today I had to catch all the other horses, tie them to the trailer, call my sister and have her help me catch her.
Even if I go catch my gelding (no attention on her at all) soon as I get close to the herd she takes off at a gallop to the other side of the pasture and starts grazing there. I've tried just following her but I end up getting tired way to quickly since they are on 40 acres. Thankfully my gelding has not picked the habit up, but my sister's filly has started doing it as well so I took my mare away and brought her up to the 50 acre lot by my house (it has a round pen, corral, shelter)
As soon as she is on this lot by herself, she is perfect. Will come right to you, follow you around without a halter, shove her head in a halter. She will come when called up here too.
