Be very careful putting a gelding in with a stallion, with mares within sight. He may become territorial and go after the gelding.
If he has not been with other horses since he was mature, I probably wouldn’t do it. I have heard a horror story of a stallion raping a gelding to death (prolapsed rectum and ruptured intestines), and would not want to take the risk.[/QUOTE]
Not sure about the raping part, as I can’t imagine a gelding standing still long enough for this to happen, but there can sure be some damage.
Usually the key is “how close are mares?” This is especially important with a stallion who has already bred. There was an experiment done just recently where they turned out some 12 stallions of various ages in one pasture (BIG pasture) and they did fine. Not one problem. They were all riding horses, so not “wild” and they were pre-introduced by being stabled together for several weeks…and again, there were not mares within sight.
And this is what mimics wild horses…the younger ones do form bachelor bands…but once you put mares into the equation you increase the chance of having conflict.
I’ve had 2 stallions. My first left when he was just a weanling and was never gelded like he was supposed to be. He was isolated his entire life till he came back to me as a late 2yr old. And he’s already pasture-bred one mare! I turned him out w/pregnant mares (no geldings/no foals) and he did fine.
But I didn’t always have a pregnant mare, so sometimes he was alone, although not far from the mares. I once tried turning a yearling son of his (gelded) in w/him, as they seemed to do fine over the fence line. BIG MISTAKE!! If it hadn’t been for my courageous stock dog, (A Rottie/Heeler cross) he would have killed that baby, because 2 people w/whips could not get him to back down. We got him out in the nick of time.
OTOH, I have his son, who is abit more mellow. He has always been in a herd. I finally pulled him from the main herd at about 18 mos and from then on he’s been in his daddy’s 2.5 acre pasture with either a pregnant mare or a gelding I bought expressly to be his buddy (to be clear, his sire is now deceased). Everyone does fine…although he likes being w/the gelding more than the pregnant mare, because she is really a bitch. At least the gelding will play with him.
In my case, the mares (open) ARE within sight and actually only about 20ft away, but so far, no issues. However he is only 3 now and never been bred, so we’ll have to see…
I will never keep a stallion isolated again, but if they’ve grown up that way, it’s a risk.
