The black cockerel with a pea comb is an olive egger, the black cockerel with a single comb is a black jersey giant, the bearded cockerel is an olive egger, and the black and red cockerel is a marans.

Thank you all

We ended up taking the two black ones to an auction, gave the EE to a friend for his flock and kept the BCM for ourselves. I can't wait to see what he looks like once he gets fully grown!
