A rooster, also known as a cockerel or cock, is a male gallinaceous bird, with cockerel being younger and rooster being an adult male chicken. Mature male chickens less than one year old are called cockerels.
I concur, that may be the biggest and greasiest black cock I've ever laid eyes on. It even has some veins of purple, if you look closely. And he looks so proud...see him standing so stiff at attention. Definitely an Alpha Cock.
So I was thinking back on my Bible studies when I was a wee lad, and remembered the story about Peter and how "the Cock crowed 3 times". Apparently this is quite the subject in Biblical circles. Problem is, I kept mixing up Peter and The Cock. And when I told the minister that The Cock "growed" 3 times, he rapped my knuckles with a ruler and threw Holy Water in my eyes which burned really bad. Man I hate church
