Want to know anyoe opinion on this or if anyone has experienced this.
I have a gelding who gets very emotional when the mares are in heat. He has never been used for breeding. No one has ever seen him mount the mares, but he will show stallion behavior, snaking his head and rounding the mares up, keeping the other geldings away. Okay, so I give him an estrogen shot in the spring and mid summer and he is good to go. Back to his old gelding self, could care less about the girls.
Now...I have another gelding. This horse has also not been used breeding. He is 20. He has always been head hancho at the barn, but he has never been study. Until this year. Late this summer, like only a few months ago, he starting acting different. He does not herd up the mares or snake his head, but it seems there a handful of mares that he has now considered his. I have witnessed him once trying to mount a mare. And again this was recent. Gave him an estrogen shot that worked so well for the other horse....absolutely nothing. It has made no difference at all. He has had several as a matter of fact with no effect.
Another twist to this story. There is a new group at our barn due to another barn closing. One gelding with this group does exibit stallion behavior, mounting, herding all that stuff. I think he challenged this head gelding, maybe to be head of the whole herd, I don't know.
The handful of mares that the head gelding has decided he likes....came over with this new group.
My question. I know my gelding was hormonal, that is why the shot worked to calm him down. This other gelding...could he be doing this to put the other geldign in his place. Kind of taking his mares away from him? It really seems he is not hormonal, as the shots have no effect on him, and he has had enough of them lately that he should be eyeing the geldings himself
I have not experienced this before, so any thoughts or opinions?
