It’s quite normal for male hogs to biff each other and even a more dominant one roll the other one up and push it along. It’s better to have more than one bowl and you could try putting them further apart, but that might not necessarily work. But you could try putting some food in another part of your garden. But otherwise the less dominant one may just learn to visit at a time when the other one isn’t there.
Quillshoggie. You might find that when there were two hogs there not fighting that they were either a male and female or two females.
