Every morning the peacocks visit me (Golden Sunset). There are now 3 cocks and 3 or 4 (hard to tell) hens. I'm sure that when the young cocks come of age, there will be some fighting. The cocks have major claws on the inside of their legs. The oldest cock is very vain and jumps on the railing of my veranda to see the "other" male in the window -LOL
Nope his head isn't missing - he's preening.
