the gray one looks pretty strange but i think the broken gray one is polish. if the full gray has loner hair is it all fibery like you could spin it or soft and fine? does it stay that short or grow a little? if it grows and is fibery they it has some jersy wooley but it is definet crosebreed.
The full gray's hair is more like soft and fine. I've only had them a couple days, but I'm thinking its hair does not grow longer than that.
GS has named them Toby and Zetti.
I would say the broken is either a polish or netherland/polish mix. It's too long in the body to be just a netherland and the ears are just a bit too long to be a ND too. So I would say you have a mix, a cute one at that though!
