introducing male mice

[Skratikans]

i have three males that i am hoping to introduce to one another, along with four females.

i know it is really difficult to introduce males together- however i have placed two males together into a completely new environment and have been able to slowly begin to introduce the rest of my mice

does anyone else do this, and what are some of your methods- how long do you keep them in their new environment before putting them back to their previous one? from experience it takes me at least two weeks

Well personally I NEVER introduced males that came from different places/litters.

I only had success raising littermates and they were together since birth.It is hard to raise males from different litters together without alot of blood!

so far so good...this definately proves to be a challenge..however i have done it countless times before

i was just wondering if anyone had any techniques for introductions
