It has roo coloring, hackle and saddle feathers and spurs. Does it crow? If it lays eggs and crows maybe it's a hermaphrodite. Seriously though..that is a rooster. If it has hens in the enclosure with it it's most likely one of the hens that produced the egg. Best way to see if it's laying eggs is to isolate it in a nesting box or enclosure alone for a day.
