All Cockerels?

[Robinparcell1]

All 4 of these chicks were hatched from our own flock. Our roo is an F1 Olive Egger and the hens are Isa Brown, Australorp, Sapphire Gem, Prairie Bluebell, Starlight Green. I'm pretty sure (95%) that they are all Cockerels but would like second opinion. The one that I am definitely second guessing is the only chick with a pea comb.
