Why is my piggy chasing another piggy?

Does anyone know why my piggy Chloe is chasing my other piggy poppy and nipping her, she is constantly doing it and I’ve had to separate them.

Hi!

Can you please give us a bit more background information. How long have you had your girls and how old are they? Has this behaviour been going on for just a few hours or for a number of day?

It is likely Chloe coming into season, but depending on the age and the length of ownership, post-bonding dominance, teenage hormones or ovarian cysts can come into play. Sows can also fall-out although it is still fairly rare.
