So I have 3 girls. The one weve had the longest is the baby, we went back to the shelter for a friend and found a bonded pair. Turns out the pair is her mom and grandma. But the thing is, is grandma piggy is the dominant one. Sometimes she just chases baby around the cage for no reason leaving her in her hidy hut wheeking and scared. Other times they're just fine. I'm afraid it will effect her health or temperament. Baby is so sweet and gentle. I don't want to separate them because mommy pig an baby get along quite well. If I just separate grandma piggy shell miss momma pig. Why is this happening and what should I do?? I've never had a problem like this before. Usually once they get along it stays that way.
