Your largest litter?

So the other day I was doing my usual rodent feeding/watering routine when I heard some familiar squeaking coming from my breeder tub. I peaked inside and I saw that one of the moms gave birth to a huge litter. I didn't want to disturb them since I saw that it was a fresh birth (babies were pretty bloody still) so I decided to check on them the next day.

I was right about it being a huge litter...24 baby mice! :O I was shocked. I mean, she didn't look that much bigger than my other breeder female (which had 13 babies today)

So on to my question to those who breed their own rodents - What was your biggest litter and how many babies survived? I ended up losing only 3 of the 24. I'm definitely holding on to some females from this litter for future breeding ;)

When i bred rats my biggest litter was 20! I was in shock when that happened:O

All of them survived by the way, for a few weeks anyway.:oops:

Ive had 16 rat pups, right after haveing 6 from another mom...weird!

24... nice. :) So far the largest known litter I've gotten was 12, but that's known. Another two moms delivered practically at the same time and the total was 30! I don't know who had how many...but I'm now almost wishing they hadn't had that many, as they are now young adults and I still have 22. :D Lucky that 3 out of 5 eat adults, then.

From mice- i had two moms together, one had nine, and when i got home there was 27:O 5 were gone withen the hext few days, but i was in show that one of them had around 18

It's strange because my two girls consistently have 15-16 babies each, except for this last litter - one had 9 more than expected and the other had 3 less. I was actually prepared for the numbers to start dropping since they're on their 5th litter and nearing retirement.

this was their first litter.

With rats the biggest litter I can remember is 21. I've had bigger litters in my mouse tubs, but since I don't separate mice I've never been 100% sure whether or not that was a single mom or a couple of moms giving birth at the same time.

wow! you guys get big litters!! my biggest litter is 9 pups only!:confused:

My average rat litter is 15, my largest was 19

16 so far out of my big mama.

I've had plenty of litters of one too. It all averages out in the end.

We average 13-16 pups per rat litter. Smallest so far has been 4 pups.

So far I've only had one female give birth and she had 14 babies. Now my other female is showing a plump belly, so I've got my fingers crossed.

Biggest litters

Rats: 17 Survival rate 100%
Mice: 18 Survival rate 100%

biggest rat litter was 19, but almost none survived, the mom burried them :(

rats, biggest 16, smallest 3, average 12

My average rat litter is 10-13

Largest - 18
Smallest - 6

We just got our first rat litter yesterday! 12 little bundles of joy. We tried mice, but the first litter was cannabalized. The smell of the one male mouse was a bit much to handle.
