I recently noticed that one of my females has been picking on my male. She was chasing him around and pecking him. I have her separated from the others for now, but I'm worried that I might have 2 males on my hands now. I currently have 1 male and 4 females housed in a ferret cage. They've been peacefully living together for the past couple of months, so I don't think it's an issue of space. What should I do if it turns out that the bully is a female after all. Will she need to be permanently separated from him?
