A rooster is a mob added by the MysticNerd expansion pack. It can be killed to drop chicken.
It has the same model as the cickenn, except the cickenn would not have a wattle, or comb. They are testured a different color.
Acts the same as chickens, except that it doesn't lay eggs. When the sun rises in mineraft, you can hear a crowing if you are near a rooster. When given love particles, it will breed with chickens. Chickens can only breed with roosters and vice versa. If a rooster has heart-particles and there aren't enough chickens, the roosters in the area will fight until there are enough chickens for all the roosters.
