I have four chickens, who are about 14 weeks each. From all of my previous knowledge, I had only one rooster. But then, one who clucks and does not have a comb made a noise which sounded kind of like a crow. It was only one syllable, and the "roosters" are not attacking each other. What is going on, and is this a hen or a rooster? Please help! if it helps they are frizzled bantam hens.
