Congratulations on your new yorkie babies, and welcome to Yorkie Talk
I have seen pics of the red/chocolate yorkies and I think they are beautiful. I am sure they are all adorable no matter what color. The good news is, there are no known health concerns for the chocolate yorkie so other than an "undiserable coat" (which I dont believe its undesireable at all) but the YTCA doenst recognize it since it is not the standard colors.
You should post pics of your babies if you can, we've love to see all of them.
I read if you have a litter with chocolate yorkies you should not duplicate the mating again. So perhaps you shouldnt mate your female to that particular male again unless you wanted chocolate yorkies again?
Good luck!
Did you read see this site before? It has some good info
