This is interesting. I got a pin girl 2 wks ago that the breeder was feeding live xl mice. I also feed on Saturday nights. I feed ft rats. I've checked my husbandry every day and she won't eat. I'm going to break down and get her a mouse, or scent a weanling rat with mouse litter and get her to eat. I also have a big normal girl and a yb boy that isn't eating. My original girl and pastel boy eat no problem. If you figure out there is a problem with the gene let us know. I want to breed her when she is big and old enough to a pastel yb boy.
