Can you put a second entrance into the food box?
To be honest as you don’t want to make another feeding station I don’t think there is much to be done.
Having come out of hibernation they will be hungry and filling up, but soon they are more likely to be chasing the girls ( assuming that it’s 2 males in your garden – and it could equally be 2 females or one of either sex )
Although the fighting is distressing for you to witness it’s normal behaviour for the hogs, so I wouldn’t worry too much about it.
If you’re lucky enough to get youngsters in your garden you’ll often see them bowling a full grown adult of the way
