Not trying to hijack the thread -- if this it too OT mods please let me know and I'll make a separate one -- but -- how the heck DO you tell the babies apart if you breed a butter x lesser BEL to a normal, or even another butter or lesser?

I always feel like I know how to tell them apart in pictures, but then the animal turns out to be the opposite of what I thought ... So I think I might have a hard time with that O.o
