I know nothing about horse behavior. I understand the nervousness around the herd. When she kept running away, was she playing with you? Trying to get you to chase/run around with her? When she overdid it yesterday was that nerves or joy?
Hope you don’t mind the questions. So glad you get to spend more time with her now and that’s she’s at a better farm. The updates always make me smile! Thanks PS: how’s her weight gain going?
