Since then we've had a bit of trouble catching her, but nothing too serious. Then Yesterday the horses were brought down from the hills for work today. She had a bunch of burrs in her coat and tail so I walked over while she was loose and started picking them out. No fuss, told one of my workers to bring me a halter to take her somewhere I can remove the burrs from her tail in peace - we're surrounded by 9 other horses who all want their share of attention. The moment she sees that halter all hell broke loose! She tried to avoid us at any cost and when cornered she swung her butt towards us.
She has no reason to have negative association with being caught, she is not a regular work horse, so being caught doesn't neccesarily mean work.
I know whe probably should have had us one of THOSE meatings right there, but I needed to get the other horses checked over, brushed out (shedding out winter coats) and tack put out. She was caught by the workers while I was catching another horse they were having trouble with, brushed out and released. We have never left her alone if she threatened to kick so no reward there.
What can I do to fix this waywards horse?
