Hi, I saw a post of facebook today about the difference between aggression and dominance and under the aggression side was a few behaviors that my pigs do. For instance, this post said that chasing and kicking the other out of hidey holes ("and not using" wasn't sure what that meant entirely) we're signs of aggressions that my pigs do. I always assumed these was playing and/or dominance. Also they said that blocking the other pig from food sources can be a sign of aggression and occasionally my pigs will block the other from one of the hay sources (there are multiple in their cage though so I've never worried about one not getting enough) but never their food, veggies, or pellets. They've never got into any sort of fight to my knowledge and these things only happen sometimes. Is this behavior I should be worried about? And if so is there anything I can do to avoid it escalating? Thank you!!
