Hi, My 6yr old gelding nips or pinches my 11month old gelding. All 3 of my horses are out together 24hrs a day accept to come in to eat thier dinner. His little pinch marks have not needed treating as they are so small and just a little hair gone. But yesterday an old mark along with a new scrape were swelled real big. Like there's fluid in them. What could have caused this? Why would there be fluid in there? How should I treat this? I put fura septin on it already. Any ideas would be appreciated.
Thanks
