I have male 2 piggies, Pancake (7 months) and Blueberry (11 weeks). They have been together about a month. They get along fine. Pancake would always grumble around sometimes but they cuddled and got along. 3 days ago I got a third piggie, Butters. He is around 8 months (I believe). Butters and Blueberry get along great. There was never any rumbling or anything, and they love to sleep together. Pancake has become a bully! He is always chasing both piggies around. Rumbling, teeth chattering...I really think he is scaring my other piggies. Is he just trying to show dominance? I think Butters is afraid to eat. Blueberry will go eat and Pancake will get on top of him and Blueberry just squeals. I feel so bad for them! What should I do? Any advice? I just don't understand because Pancake liked Blueberry before, now he is bullying him! Help!
