7 Barred Rocks--double checking gender at 5 weeks

[sarahandbray]

Would like to give my male Barred Rocks to a friend or put them on Craigslist. Out of the 7 McMurray sent me in the "special mix," I think 6 are boys!
Can you please confirm? First pic is all 7 together. Clearly, 4 are super light, two are darker, and one is almost all black. I've put them in number order from lightest (most likely to be male?) to darkest.
Don't want to give away any girls as I think I've had horrible luck already with Straight Run!
And at 5 weeks, can I offer them for free on Craigslist in groups less than 6 for local pick up?

Shoot. Well, it went out of order somehow. Grrrr...

(7 is the only hen, right?!?)

1,2 & 3 cockerels - I find 4 questionable

X2 #4 has a darker comb. I am thinking male.

#1, #2, #3, and #4 look like cockerels to me. For sure, the first three are.

What tells you the difference between male and female?

What tells you the difference between male and female?

With barred rocks the males are generally lighter in color. They have more white. Pullets would not have such red combs at 5 weeks old!

I do agree that #1-4 are cockerels. (4 being a little questionable, but probable.)

Thanks! Will give them away lightest to darkest
What about 5, 6 & 7?
