On identifying a cockerel, generally speaking, if I ever think…hmm, is that a rooster, they generally are. If they have much redder combs than their flock mates, they are cockerels.
But I have had chickens for decades, and three years ago I did not identify a cockerel until he was more that 4 months old. I swear he grew the tail, the saddle feathers and the crow over night.
So it is a far from perfect. Do make a real plan for what you will do with them NOW, before you have trouble. And the reality of keeping both in a peaceful flock is not probable.
