Hi All, I am raising my first flock of chickens so hopefully my question is not to silly. Anyhow, I have a BO roo that is about 6 months old. He knows I am the alpha roo because when I go into the pen he makes sure to keep his distance away from me and does not come near me. But lately he is making this growling noise as he goes to the back of the pen when I enter it. Is this a noise that all roo's make or is he mudering under his breath at the fact that I am in the chicken pen. What do other roo owners think? thanks.
