Sweetpeas Behavior Problems

[Cinnamon]

Sweetpea... sad to say it will have to be given away,she has gotten very jealous, and attacks Cinnamon, Chocolate and babies!
She was a rescue piggy, but we don't want her alone again, Because when she lived with another family, She lived with her mother who ran away, I really want to keep her, and get her a friend who isn't pregnant, a neutered male maybe? Poor Sweetpea....

We have grown so attached to her... What do we do...

And also we have had her for over a month, also Cinnamon and Chocolate we have had for over a month, nearly 2 months. They have changed but she hasn't.. She bites you, She bit mum and mum had a bleeding finger and it was painful for her.
