Seperating Mice

We have a female mouse who has 3 week old babies. When should we pull them and seperate them into the feeder tanks?

You can wean the babies at 3/4 weeks.

According to rodentpro, weanling mice are 21-25 days old. And "large adults" (is there no such thing as a small or medium adult mouse?) are 30-40 days old and sexually mature.

I guess if I can see them munching on Mama's food then its time to seperate them.

I just cleaned thier cage and the babies are nibbling on her food. I'm going to give them a few more days. Thanks for the help.

I separate them when they no longer have that 'baby' look. They look like adults only slightly smaller. Usually about 4 weeks. I HAVE separated them too small before and they ended up starving because they didn't know how to feed themselves yet.

Jay, I would assume in this mice are likely much like rats....the babies will start trying mom's food and her water bottle but also will still actively nurse off her. It doesn't hurt to let them have a bit of time getting their nutrition in both these ways so they are nice chubby weanlings when you do pull them.

Just make sure they are off momma and seperated by gender by 5 weeks of age.
