Thanks for the reply. She had an umbilical hernia as a pinky/fuzzy so that may have contributed to it. The other two are growing well.

So is mink recessive? I looked it up on a rat genetics site and it says mink is represented by m while the normal M is the non-dilution allele. So as long as each parent carries mink, you might produce a mink.

I will try the pairing again and see if I get any more minks from them. I LOVE the color. Of course Noel's first litter was not very big but of course it was her first litter.
