I hatched out chickens, I thought most were hens now I don’t know. They are 4 months old and hatched from orphington eggs.

The first three birds look like cockerels to me. I'm uncertain about the black bird - can't see pointy hackle or saddle feathers, but the tail (never a good indicator) looks a bit suspicious.

I agree with sourland, but pretty sure the black one is also a cockerel. Those are terrible odds but it happens sometimes.
