Asia Black?

[Bilppen]

Was sold as an Asian Black. It isn't a sex link.
Some of the chicks have FIVE toes, I'd really like to make this clear. They could be roos, but I can't tell. Maybe a silkie cross?
They have very thick bodies and legs. They're way fatter than my 3 week leghorns. Combs are somewhat large, but not very red. One of them has a full black comb (not shown in pic)

Sorry, these photos aren't the best. They're about 3 weeks old.
If they're Asian Blacks, I'd love information about sexing them. Chances are, all of my chicks are roos, hence the thick legs.

Sexing will probably be easier when they're a few weeks older yet.
Black combs make it harder, because they don't turn so obviously red as normal combs.
Thicker legs than Leghorns might not mean much--most breeds have thicker legs than Leghorns!
