Barred Rock head spots

[Nizina]

I ordered three straight run barred rock. I have watched every YouTube and am still not sure of the sexes of these chicks. Two weeks old. I’m guessing one pullet and two cockerels, but not sure. Please let me know your thoughts.

IMO, head spots are only useful if you have a big group to try and pick the most obvious pullets from the bin. There are a lot of chicks where it isn't so clear. Look at the mess mine had; would you have gotten pullet from just the head spot?

I'd expect at 2 weeks they have enough wing to get some clue from the barring, it only gets more obvious as they feather.
