breeding mice??? HELP!!!

I don't think inbreeding with mice is much of an issue, it is done all the time with lab mice and they are inbred for hundreds of generations to make them genetically identical. They still seem to breed and reproduce just fine.

I've been breeding mice from the same original stock for about 2 years now and they are all breeding just as well now, if not better, as when I got them.

You should have just 1 male with each colony, and once you put them together you really shouldn't move them again or you will have fighting and possibly lose some of them. Plus every time you move them around it will delay the breeding that much more as it takes time for them to get used to each other.
 
well thANKS for the help but the second male i have nuthing to do with so im thinking i will just feed it to my corn snake... haha i think one of my female mice might already be pregnant but i will just have to wait and see.. i will post pics when i get a camera...
 
You can save the excess male in a solo cage or tub for a replacement in case one of the other males doesn't make it.

I am raising Swiss Websters. I started with 5 males and 25 females 20 years ago. I have raised 10s of thousands of mice from those original 5 males.
 
I wish I could find some genuine Swiss Webster strain mice. Plenty of plain old albinos with relatively good sized litters but nobody seems to have genuine Swiss Webster.
 
Swiss webster

Just wondering about swiss webster? Is that a strain of mice from a particular lab or something? Do they produce more than normal amount of pups? Since I got into the breeding thing very new to breeding mice but I have some albino and 2 of them produced over 35. My fancy female and the other two all had the litters on the same day and the fancy pups are like half the size of the others.
 
Swiss Webster is a lab strain of albino mice, bred for large litters. Supposedly they can have litters of over 20, up to 30. I've heard their gestation period is a little longer as well.

I've had albino mice that frequently drop 15-18, but no idea what strain they were.
 
I bought my Swiss Websters from a lab supply in New York. I purchased 30 mice and paid $5 each for the mice and I think the freight was $200.

My mice on average have 20 per litter. They almost always raise them all to weanling age. I have never had a tumor or illness of any kind in my mice. I'm real happy with them. They were worth them money.
 
:grin01: I'm sure glad my snakes are not picky about color. I have fancy mice, all different colors ( tan, black, grey, brown ; short and long fur). :headbang:I would be in big trouble if they only ate white ones. I get 10 to 14 babies from each female. I had 1 female that had 18 babies. They wer really small. Great for tiny hatchlings.
 
I put vitamins in my mice water . I know that My Snake is eating healthy food and they don't need anything else.:eatsmiley:licklips::eats02:
 
I would be careful about vitamin supplements. From what I understand you can easily overdo it with food supplements. If the animal can't metabolize the vitamin or whatever it can build up to unhealthy levels and become toxic.

I know nothing about breeding feeders, but I read in one book to use vitamin supplements for hatchlings at every meal - then a different book said that you should not use them too often because they may not be absorbed completely and build up to unsafe levels (an exception was using calcium supplements with females before breeding to prevent egg binding).
 
Well, for that kind of price I guess I'll stick with the albino mice from the local reptile show. I think they were $0.60 each and I got consistent litters of 15-18, sometimes as high as 20. They're probably swiss websters anyway, or at least partially, though the breeder didn't know.

I checked the Harlan website, but they seem to only sell for research use to professionals.

Currently I have a range of colors, my most tame breeders are cow-spotted long haired satins, which are pretty cool looking and very tame. They have about 10-15 per litter, which is really big enough for my use. They were outcrossed with the albinos at one point, so they are descended from the albino lab strain. Longhair satin albinos pop up occasionally.
