Also, as far as when they start developing the pointed saddle feathers, it seems to vary even among brothers from the same mother and father and same batch of eggs. One of our older ones started crowing and getting saddle feathers at like two months old. The other two from that batch didn't start getting their saddle feathers until 3 months old and still aren't crowing. The two younger ones started getting their saddle feathers and crowing at exactly two months old and were sparring and picking fights with the others and really getting obnoxious by 3 months.
