need more help with breeds

ok so I have 2 chickens that are pure white and are REALLY fluffy, they do not have featherd feet but they have small crowns (probably just the hen factor) they are soft and are farily big for their age (11 months ( not laying yet) and bigger then the rest of my hens (i have a buckeye, silverlace, Light brahama, Red star's, and i THINK brown leg horns.) )

Do you have photos you could share? From your description, I'd say to Google "Silkies".

they're not silkies to me they look like Rhode island white

Here's some pictures

Wyandotte and Orpington both have a white version. The difference would be in the comb, single vs rose. I think I see a single comb in your picture but I'm not sure.

There are a whole lot of variables that go into your question. We're they raised on your farm? We're they bought as chicks? From a hatchery or individual?
The white may have come from white rooster hopping over into the neighbors pen. The breeder could be careless with egg handling. The breeder could be breeding a little to tight (inbreeding) causing a "throwback" to a color that went into the making of the breed, or maybe a hundred other variables. Or it could be simply that you bought a variety of chicks and you got 2 white somethings.

they do have sing comb

So the Orpington is a possibility in that case. Tracy has a lot of good questions that can help narrow things down in her post.
