I guess it just depends on the horses.
Exactly right. Where I board, it is of course their business to keep horses safe and they usually have geldings together and mares together, but with careful supervision when they are first introduced, they will mix sexes. Tosca was put in first with her Icelandic buddy Lina, plus another mare and a gelding. The mare ran her all over the pasture. Given enough motivation, Tosca does a flying pace. So we pulled her right back out and put her in with five geldings. They all did just fine. Later, another large pony mare was added to the mix. The two ponies hang out together. They're really sweet to watch. Nancy
