Hello! I got my first piggies about a month ago and managed to get 4 baby girls (all sisters.) All was well until a few days ago when I noticed one of them was sleeping separately from the others (they were all sleeping together before) and she just wasn't acting like her usual self. I sat and watched and realised one of my other pigs has been chasing her, tooth chattering etc. I thought maybe she needed to let of some steam since I hadn't seen this behaviour before so I got them all out for free roam but the bullying continued even then. I checked the bullied pig over and she seemed to be fine yesterday but I've just gotten them out for free roam again and she now seems to have some scabs on her butt. I'm really concerned for her as she seems pretty distressed by it all and I'm not sure what I can do. They are about 3 months old now. Is this likely just a hormone thing that will pass, or should I be separating them into pairs? There seems to be no bulling amoungst any of the other pigs it's just the 2, and is always one sided. Any advice would be welcomed. Thank you!
