Having a rodent colony is DEFINITELY the way to keep yourself amused while waiting for the BPs to get big enough to breed, or to breed, or lay the eggs, or for the eggs to hatch! I have all kinds of fun with my mouse colony, and all the colors I can get out of it now.

Of course, it is dangerous, too. I now find myself wanting to try to find some show mice breeders so I can get some of the really fancy colors. LOL.

Your babies with the spotted heads are really adorable. Are you aware of the risks of megacolon when working with such high white rats? I don't know much about it, but I know some people prefer to avoid that kind of marking just to avoid the issue, but I believe others have had success establishing high white lines that are free of megacolon.
