So I had one mom who had 2 babies only, a boy and a girl and they were born 2 days after another litter with no runts. The girl was a runt and now named Peanut, and the boy was chunky (now named Bubba), even from day one.... Should I be worried? I mean, he's really big, even compared to the babies of the first litter he's bigger than them and has been. You can pick him out even without the markings because of his size. Is it something I should worry about?
