Female mouse bully

[Ladybugzcrunch]

One of my female mice is bullying the other females. I removed her because I was afraid she would injure one of the others. They were all introduced to a new enclosure together. She is the friskiest (vibrates her tail a lot) of the group. What should I do, put her in tomorrow? She has been bred, about 14 days into gestation, should I wait until she has had her litter then reintroduce her to the colony? I may have ruined her as I had to remove all the other females for a while and she was alone with the male for about 2 weeks. She seems jealous?

She may just be territorial from being bred, and pregnant. I'd let her litter alone, and raise the babies, before trying to re-introduce them.

Make sure to introduce them on neutral territory, as well.

Welcome to the wonderful world of breeding mice...

If she is bulling other to the point of injuries, feed her off

Getting rid of bad elements such as biter and ultra aggressive individual is the best solution.
