I still wouldn't breed them, since you don't know their whole lineage. I never feel comfortable breeding rats that came from pet stores, since you don't really know where they came from, or if they have had problems before. Sometimes I don't even feel comfortable breeding my rats with pedigrees, if that says anything.

You could probably keep the girls as buddies for the resting females, and the boys as friends for weaned males.

Rats that aren't considered high-white are berkshires(white socks and white belly), selfs(no white anywhere), hoodeds, irish(white on chest), english-irish(white on chest and tummy but not feet), siamese/himalayan. Yours are good examples of high white: first one is a possum marked, second is a variegated w/headspot(anything with a headspot is considered high white), and the third is something that I'm not familiar with, might be considered a low quality dalmation, I don't know...
