So I have two females and I’ve decided to introduce a third one. What I’ve thought was my dominant one (cookie) only chased the new one once or twice the first couple hours and didn’t mind her anymore. My other piggie (pink) in the other hand, chases the new one constantly. I notice it’s only chasing no teeth chattering. Is the behavior normal? How long does it last? Is the piggie doing the most chasing the dominant one ?
