Here are some updated pix of Babs' and Chuck's babies at about 3 weeks. You can't see them, but Babs has her second litter hidden in a nest under the surface of the bedding. It took me a minute to locate them as they were pretty quiet until I disturbed the older baby who was warming the nest, at which point they let out a chorus of tiny eekings.
I had thought, when I first got tricolours from a breeder in the NYC area, that they were new and rare. By now, I've found that they have been around for decades in some form or another, and are available in distant parts of the world. It is not unlikely to think that they'd be available from a breeder in the southern California area. A guy on the Little Squeaks forum turns out to have them and didn't know it until I told him that the splashed type of marking is based on the tricolour factor. He's in Michigan, I think.
I'd be happy to share the wealth with anyone who was willing to come and get them in person. I offered some young tris to a guy that wanted a couple of does, but he wasn't interested. He got a couple of my satin fawn does instead. Since he waaasn't going to breed meeces, it doesn't make any difference, I guess. I love to see more folks breeding tris as it would help us all figure out exactly what's going on with the tri factor.
Truth be told, I'm beginning to suspect that there will never be any way to predict the outcome of pairings with any high degree of accuracy because of what seems to me to be a built in randomizing element, or multiple factors that behave differently depending on several other factors that may be genetic or the product of environment or diet.
if i ever came your way i'd love to get some of your tris! hahaha. there are no breeders near me at allllll. which is why i just had to get feeder mice. someday i'll be able to get mice from breeders though.
it would be nice to figure out the genetics part completely. im still just learning the basics of genetics haha. i wish i knew how tris worked. i'd love to see if i could make them. but of course it seems you need tris to make tris. maybe i'll get lucky and one of my feeders will have this"tri gene" in their background! that would be crazy though. but i can always hope!
Some day, hopefully in the next couple of years, I'm going to make a pilgrimage to RodentFest. I can then spread the wealth from my mousery and pick up some new quality blood for my mousery. I'm getting tired of pet store finds that just aren't healthy enough to ever make it into any of my breeding plans. I've come to think of those occasional purchases as rescues from the crowded conditions in those places. RodentFest is where my tris came from thanks to a NYC breder who hand delivered to a breeder from Wisconsin from whom I picked them up.
