I have a question. My mother-in-law has a 13 year old horse that was gelded 1 ½ years ago. He was used for breeding before; in fact my mare had a foal of his 2 years ago. Well, he is now living at my house for the winter (our cows are at their place) in the pasture with my mare. I caught him completely breeding my mare today, a couple of times. I know she cant get pregnant or anything what I want to know is if anyone has any tips on stopping this behavior. The neighborhood kids dont need to witness this.
