what breeds can be color sexed?? Swedish Blues?

[barnyard betty]

Hello everyone...are there any breeds that can be sexed by their down color or bill color etc?
Also, I think I may have Swedish Blues...but I'm not even sure of that, they are grayish on back and head with yellow belly and some have black markings on feet and bills. Is there a color difference between Swedish blue and Swedish Black & White as ducklings? Or does it not become obvious until they get feathers?
P.S. If they aren't SB...then what else could they be being gray and yellow?
Thanks for reading!

I do not believe SB's can be colored sex. The only sex linked breed I know of is WHs but that is bill coloring.

Hummm...ok, I thought so, it was just a thought...guess I'm gonna try my hand at sexing the other way lol!
Any ideas on if they are true SB or what?

Do they look like this?

YEP! They even have the goofy smiles lol!
Some are more grey...some are more yellow in the yellow parts and one is black on top with yellow bottom.

Then they are defiantly most likely Blue Swedish. A very beautiful breed!
