I had a good friend raise some Sumatran chicks for me. Just got them, 3 out of 5 straight run chicks made it to teenagers (3months old) I was hoping for one good rooster out of the bunch to look after my mixed flock of hens and maybe turn out some interesting offspring. The one i think is a cock is big and feisty, iridescent black- but with a few white tail feathers, and looks like the start of spurs on it's legs. Anyone want to guess if he's my boy?
