I hate to tell you this but both of your Yorkies are standard one of them can't be minature since there is no such thing as a minature Yorkie. The Standard is stated as any thing UNDER 7 lb. So a 2 lb Yorkie is just a standard as a 6 lb yorkie.
You will be able to tell more about the pups grown up weight at 8 weeks. There is a growth chart here on the general discussion page and also one at yorkiepassion.com.
Best of luck with your new babies.
