How to sex a frizzle???

[Magicbubble]

Hello please can anyone help? Who can tell me what to look for when serving frizzles?

Here are my two. Patch has more white on the face and legs. Cheepy is just black.

8 5 weeks old and pekin crossed with Araucana. Here is my straight father one as well if anyone wants to guess that one.

Those red combs mean roosters on the frizzles, the straight may be a pullet.

The straight combed one has feathered legs, maybe cochin behind it.
