Sexing Wild House Mouse

Question
Hello =)!
I have four orphened house mouse mice I know for pet mice you can sex and seperate them about 4 weeks but for a wild mouse should I seperate them sooner maybe 3 weeks? I just dont want any unexpected litters and I am not sure how soon a wild mouse can breed.

Answer
Dear Nikki,
thank you for your question and I apologize for the late reply.
House mouse can stay together for four weeks, but since they are orphaned anyway, you can separate them sooner just to be on the safe side.
I hope I was of some help to you
