We have integrated quite a few males into our gelded male herd over the years. I have recently bought two paddock mates in slowly (1yr and 2yr). One of our 3yr old gelded males has taken possession of them and is trying to breed with them. the 2yr old is the one who cushes. The 1yr old seems to have a handle on it doesn't let him mount. The 3yr old won't let any of the other boys near them. When he is not trying to mate, he is only a few feet away from them. We tried isolating him, isolating them, and letting them work it out. Nothing changes the behaviour. Here is the weird bit; This male came to us with his paddock mate when they were both just over a year old. The brother was unwell and never grew. He had genetic health issues and later died when they were 2yr. Throughout the year we had them both, the brother acted like he was weaned onto the other male. He would cower along side his brother at any sign of fear and was fiercely defended. They were never more than three feet from each other. After the brother passed away, there was no behavioural issues until the new two arrived a few months later. It seems as if they have been adopted by him. If there wasn't the mating issue, I wouldn't be concerned at this stage. However, not only does this male not leave their side, now the two new boys get distressed when we isolate the him from them. They won't go out with the other herd members and cry constantly. I am very concerned. I can't say that I have any solution to this other than rehoming him. I have never rehomed any of our pets and can not bare to think of it. NOTE: We have 17 gelded males from 3yrs to 22yrs. I have never been unhappy with integration over the years and do it slowly and only progress when I am confident it is safe and appropriate. I now feel very desperate to do the best for them but I don't know what to do. Please help me figure out what is best for them.
