I have had one of my geldings for over a year and he has been with 3 mares and he thinks they are his little harem. (He's arab/quarter). I just brought a new gelding home that is older and he's in the pasture next to him. My Arab/Quarter does not like him near the fence and keeps charging the fence after him. I need to be able to put these boys together. Does anyone have any suggestions on how to get these to like each other. I did put one of the girls in with the new gelding this morning. I don't have the space to keep everyone separated.
