I've just started out breeding mice for my collection of ten permanent corns of my own and two non feeders I'm having a pop at for a friend.
I've had them a week and so far and have done even more research since getting them. I also euthanised my first adult today so I can share my findings from it all
I currently have two males and two females. I should have had five females but two were sexed wrongly. It was one of these I euthanised earlier as males can fight horribly when together. I used the cervical dislocation method and it went pretty smoothly.
So one of the females came to me most likely already pregnant. She looks it and acts it, and weighs 42g which is more than any of the other three. She is currently housed with one of the males whome I will remove before she delivers.
The other female is with the other male and fingers crossed is now pregnant. Again, he will be removed before she delivers.
I get all four out for communal, supervised play on a table top with loads of toys once a day in the evening. Aside from it being lovely for them (and for me to watch!) I am very conscience of keeping the two females happy together as I want them to live together in the future. The reason I haven't put them together yet is because I'm not 100% comfortable doing so close to one giving birth. I don't want to increase the risk of baby munching, and everything I've read so far suggests females need to be bonded well before they can be "nannies".
So the goal will be to *attempt* to sex the first two litters and all bucks will be culled. Aside from needing pinkies for three hatchlings, it's recommended litters be culled to manageable numbers for the mum to rear them. I will then allow all females to reach adulthood and probably keep some more to breed so I can cycle the females as that's better for them than constantly producing litters.
I will then keep a colony of does and two separated bucks (one for back up) and they'll be housed in a roomy cupboard to combat any marking odour. Also a third enclosure to act as a "shag pad" so not all does are impregnated at once!
I currently have two enclosures in my living room and can honestly say the smell produced is minimal and nothing a scented candle can't cover up if need be. We had visitors yesterday who couldn't smell a thing so I was pretty happy with that.
Constant cleaning out of bedding only encourages males to scent everywhere again anyway, so I spot clean and remove any obvious wet bedding.
I'm currently using up what they came with, but will be swapping to this:

You can't complain about 20kg for under £20, so I can't understand people who say they'd spend the same amount of money on bedding as they would on pre frozen rodents? I got three water bottles for under £5 and I feed a mixed diet including seeds and dog kibbles. I'm also offering my pregnant-for-sure female some scrambled eggs and can't say it's costing me a lot at all!
