Ok, so I have a single pair of breeding gerbils. The female is a black and white, and the male is a gray and white. They had a litter of 6 last week and the babies are a week old. They are just getting their fur in and are so soft. I can't tell sexes yet, but it seems to be an even spread of black and whites and gray and whites, though there is a baby that looks to be solid gray, so I might keep that one. I plan on keeping at least 2 from this litter anyway. Pictures to come as soon as I can take some. Every time I try and take a pictures of the babies, the male steps in and shields them from the camera.
