I have a litter of babies that are almost 2 weeks old, and of course, I had to have a runt in the litter, however, even at almost 2 weeks, he has no hair (except whiskers) and when I held him yesterday, I noticed that his eyes are opened, and his bigger (double his size) brothers and sisters still haven't opened their eyes. I thought the runts are supposed to be later in developing than the "normal" sized babies? Is there something wrong with him? I also noticed that he runs in circles, which I have never seen one do. And he has a black mask across his eyes, and black on his back, but still no hair, almost like a hairless rat. Any ideas/suggestions would be helpful. Thank you in advance!!!
