Hackles in EE's can be really deceiving. They can look really pointy based on the coloring, but when you look at them with a piece of paper up under a couple of feathers you can see that there is more feather that isn't readily visible because it's very light colored. So what looks like a pointy hackle feather is actually a rounded feather.
In the picture with the 4 of them in it, I'd guess the three on the right are pullets. I've got pullets exactly those colors right now, and I don't see any comb development on those three. The one on the left, by the comb, I'd guess cockerel.
Of my twelve EE's that I recently ordered from a hatchery as pullets, I got one with a crooked beak and three cockerels. Grrrrrrrrrrrrrr. Sorry about all your boys. Are you up to butchering? Or just going to re-home?
