There is an older saddle horse that roams with the mares. I have never seen the mares accept him or interact with him unless it’s to chase him away, until now …
As if they have been friends forever, this mare approached and groomed with the gelding. Of course it’s possible that this behavior occurs when I am away, but I have only seen a lack of tolerance with all the mares in regard to closeness with the gelding. He’s a good guy so I was happy to see this.
