Do you separate pregnant mice?

[amon]

After reading that again I thought it might be a little confusing, I mean I do not separate

Ctrl, So you have a bin full of mice and once you see pregnant mice you put them in a different tub with other pregos? Good idea if im not intercepting that wrong I think I might do that actually, my rack gets annoying and Ive wanted to put all my mice together.

This part is not confusing, but your title question and the poll answers is switched, you see what I mean?

Back to serious. I keep them together, even the male.

My experience is that any new comer to an established group will get biten, sometime till death, both male and female. I envy you can move your male around.
