Ok, so I am uploading pictures as I type this but I have another question. Is it possible for an Albino Rat or mouse to have colored babies? I was at the pet store yesterday and while they were getting the rats I noticed they had 4 or 5 different mice in there with litters 3 of them were albino and half the babies were colored and the other half white. So I was just wondering, is it possible for 2 albinos to have colored babies or will two albinos always have albino babies?
Yes. They MIGHT carry "hets" that would make colored or marked babies. No way to tell unless you breed father to daughter and breed at least one pair of full blood siblings.
Looking at rat fansites is going to get you "quality care" crap. Throw the rats together and see what happens. Females start having cycles at different ages, so I let them decide when they start breeding.
(IMO a year old rat has lived half her life. It's like a human having their first kid at age 50, or something of the like.)
If you want to be careful, which I think you might since this is all new, wait about a month. They look about 2-2.5 months old to me. 4 months is the age feeder breeders recommended to me, though I had one girl who did better at 3 months than a sister from the same parents who was 4.5 months old.
I think your rats may be at an age where they will still double in size and weight, though the buck will probably triple in weight, as they're thicker than females. Another thing about this: cull female pups and feed those to your pup eaters. Raise the male pups up for your larger sized eaters (BPs).
A local breeder here has a website that says she doesn't breed until 6 months, gives them a month to nurse, a month to recover, and then breeds again. This is BS. Unless your female gets skinny, which will probably happens with their firsts litters, keep them together. If a female doesn't recover from a littler within 2 or 3 weeks, don't keep breeding her or keep any pups. One of my girls would NOT wean her pups and some older pups (I kept her away from them for a week and she was STILL lactating), continually lost weight, and had a seizure from her health.
Another thing-- if you have a female lose weight like that but she's not super skinny with her backbone sticking out, try introducing fatty foods to her. Bird seeds, yogurt, cat/puppy food is all great choices. I prefer yogurt, as I see results with it immediately (except for the one that seized).
