Ways to rotate mice...NEED HELP!

[Herp4life11]

I have a 18tub rack and I am going to run a 1.2 in 9 of the tubs and use the other 9 as birthing tubs for prego females. I want my females to have a one week break in between nursing the pups and starting to breed again. I have a genral idea of how I will rotate them though the breeder tubs (1st 9tubs) and the birthing tubs (other 9tubs) but, I have been trying to put this on paper and my my brain just wont let me do it. I've been going crazy for the past 2 days trying to do so

I was wondering if anyone would lay it down for me so I could see it

I would really really really apperciate it

Thanx a lot and sorry if this is a bit wordie.

Why rotate mice? they do best in colonies, and left alone.

Just leave them all together, find a combination that works for the particular bin. Some may be 1.3, some may be 1.8, others may even be 2.5, etc etc...
Find a group of mice that work well together, and let them populate.
I have some bins that are literally 3.15 with dozens of babies. Take out a male or a few females, and they start in with the cannibalism... It's a fine line with some, and doesn't matter what you do with others...
I harvest about 400-600 mice a week in 60 lab cage colonies.

I ment like when you have them set up in a rack set up.

Thats pretty wierd how you have sometimes 2 males. Ppl usually dont promote that because sometimes the males will fight and injury themselfs/kill. Also they might eat thier babys...

How do you run a 2.15 in those little lab cages? Thats about 150 pinks in that size cage?

Holy SNIKES! That's a LOT of mice!

Like I said, every cage has it's own dynamic structure.
Yeah, at times, a couple of my cages can look like a horror film full of mice.
Males are generally just one per cage, but at times, a baby may get left in and grow up. Most of the time, the skirmishes are with newly introduced females.

As for a rotating rack, I'd still just run a small colony in each bin, and be done with it. Pull the weaners out on a regular basis, and they should be fine.

introduction of new mice MANY times results in death.

Setup up a colony and let them be.

I personally recommend you only pull weaners when you are cleaning. It changes the scent and environment and causes little problems. Just pulling weaners has shown me a reluctance of reproduction or a tendency for mothers to kill their offspring.
