Eh, I leave mine in after they've given birth. *shrug* I'm interested in numbers mostly. No mice ever go to waste at my house, and usually I'm running a "just in time" policy it seems.
If you're breeding for pet mice maybe, but for feeders I don't think it really matters. As long as they have a really good diet, I don't see the issue in waiting.
That and if you leave the male out for too long, you may have issues re-introducing him to an adult female.
Not to seem to rude, but most of the questions you're curious about have been discussed at length previously on the forum. All you have to do is use Search and enter the keywords you're interested in.
And PS, the whole caps lock dealie is a little much. We see your posts just fine without you "shouting" for attention.
