Sorting out cockerels

[cren21]

Hi! I am attempting sorting out cockerels from my straight run purchase. They are a backyard mix of marans, and buffs...maybe some olive Eggers (?) At least that is what they appear to be. They are close to six weeks old. I am hoping to take the cockerels to auction this weekend. If there are any that are not sure, I will wait longer. There are already 3 that have confirmed themselves over the past couple of days. These are the questionable ones. The black ones all look like crows and are pretty much identical in size and color, which makes it hard to sort them out. Pics were difficult, so best guesses are welcome
I am hoping the white one and the tan one are maybes, but I have my doubts...I have a few more that are on the brink, but I'm okay with waiting a bit for them. Thanks!

The only one I'd guess to be a pullet is the first black one, all the others are looking like males to me. If you have any doubts just take them to auction anyways, if you have plenty to spare at least.

Thanks for the reply I do have room to spare…I was just hoping I was wrong about the white one and the tan one bc they have a good temperament right now and the kids like them.
