WELL I'm sure whatever problem was going on is too late for me to try to help out with since it's been a few months.... But for anyone else who may look at this, I'll just stick this out there.
So recently I bought two feeder mice from the petstore that's practically around the (long) bend from my house. (I was originally going in there to replace one of my hamsters, but there weren't any cool looking hamster coat colors/patterns I hadn't already had.... I'd never owned mice before, and they looked really cool and unique with their splotches of color.)
No mix up in the gender despite still being pretty young, but they were both pregnant. I have 15 pups who will be 5 days old tomorrow morning, so of course I'm doing research about what to do for them once they get older- there's no way I'm returning them knowing they'll become snake food.
That being said, I did enough research to make it hard to find anything new to read about them.
It seems 50/50 about the male mouse thing- some say 'don't house them together, they will only fight', while others argue that they've housed many male mice they've raised together for their whole lives without any major issues.
I'll then presume that the issue is that you need to make sure they have enough SPACE and toys/feeding areas so they can claim different areas for their own. Most cages you can buy for mice at the store are only big enough for maybe two male mice, which will make fighting more likely.
I'll most likely end up with keeping all the male mice in my litter (I attempted sexing them today, and my prediction is that I have 6 males and 9 females- we'll see how correct I was in a week or so.) since most people just don't want to deal with their over sized testicles. I honestly am not a big fan of it either, but male rodents tend to be darlings personality wise. (least in my experience as an owner.)
Anyhow, I suppose I'll let people around here know my experience after a few months go by- If I must I'll seperate them into cooperating groups or even single parties if any are getting real abused, but that'll be my last resort. I'm actually going to make my own habitat for them and toys and such (I'll probably use old hamster and guinea pig items I have lying around doing nothing) to make sure they've got their room- I'm pretty strong in believing this hypothesis of mine, but again we'll see.
