I'm kind of new to breeding rats. Currently I have a trio of 1.2 breeders only one female has given me a litter. The other is a newer female I just recently introduced to the pair. All being mostly white with few markings I wish to ID if possible..They are primarily bred as feeders for my various snakes tho but I've been asked to breed some rats to sell a bird shop in my town as pets. My question is should I start a new group of breeders for pets maybe use blues? I recently read high white rats bred together can cause problems? Should I get rid of my current trio also for solid colors? Even though the babies they gave me seem healthy at one month of age now?
