Roo or hen for these EE’s and BLRW.

[Crazy for Chickens!]

The Wyandotts and the white EE are cockerels. Rest look like pullets.

I think pullets

The light gray one, I don't know! If I have to guess, at 13 weeks old, roo, based on that bar shading on the wing and the size of the comb for an EE. The dark gray I would guess is also roo based on body posture, comb, and that tail! The white one is a little harder to see the comb..... But I think that coloring is typically male coloring. I wouldn't get rid of any of those EE's quote yet though!

Side note, I see you have a pullet BLRW there. Use her to compare your coloring for roos vs pullets and see if you can see what we mean about the color patterns. See how she still has the white lacing on her wing and back while the roos in your original pics the lacing is gone and you just have the red color?

The black and blue in the last pics are cockerals
