Help with my ducks

Hello, I have two female Perkins, they just turned a year old. My problem is, one of them is holding the other down and chases her a lot, do I need to separate them, need help. Thank you

Hi @Northerncaligirl...
How are they doing today? Are you sure they both are girls? Can you post a picture of your ducks?
