Stunning!!!!It is a cockerel because of its coloring. Pullets will be laced all over. Cockerels will be darker with lacing only on the chest. Yours is a hatchery bird and not colored very well so you will not see one like him probably. But the silver in the wings and in the hackles is a cockerel thing not a pullet thing.
My birds are from a top breeder in the country so they have a lot more silver but notice they are NOT LACED except on the chest.
