I recently adopted 2 skinny pig sows that have been litter mates since birth. They were shipped to me from Illinois (I’m in nyc) and in the carrier, one girl scratched the other pretty badly. She had small scratches all over her back that were bleeding. They have been with me for about 4 days now and I keep seeing aggressive behavior from the one girl to the other. She takes her food, pushes her out of their hideout, and continues to add scratches to her back. Could the stress of the trip and rehoming caused them to all of a sudden not get along even though they did before? Should I separate them or let them sort it out?
