I found a horse in a field near my house injured. There were about 6 other horses gathered around it and they were nipping at it, one actually put his leg in his mouth and they were nipping at his neck. I had to get a big tree branch to chase the other horses away so I could get to the injured horse. When I was able to get to it, it had a few bite marks on its neck but mostly wet hair. One was actually on its knees, kneeling down to the other horse---I know this horse was old and sick. Have you ever seen anything like this or do you have any idea if they were trying to help it get up or if they were hurting it?
