All cockerels. The bigger of the two youngsters has male-specific coloring and the smaller has too much comb development to be a 2-month pullet. The older cockerel has rooster feathers.
All cockerels. The saddle feathers are quite pointy and they have male features. Also, their comb is bigger than most hens their age, same for the legs.
Well, no question (though there wasn't much) for Slush. He started crowing today. Will have to decide what to do in the near future (we're not supposed to have roosters where we live, though how loud he is would be the main issue there) He's a mixed breed (of I don't know what), so I don't think there'd be much demand for him as breeding stock. I'm leaning towards eating, but it would be the first time for us doing anything like that.
