Q. I have a male burro that was gelded about two years ago, when he was approximately 7 months old. He has always been housed in the same corral with two horses (mares) and one jenny (his mother).

Sometimes, the male burro will actively mount the jenny. For example, today I had to go outside and break the two of them up because the male burro was mounting/mating with the jenny. He will not try to mount the two horses, just the jenny. This has happened off and on since before he was gelded
