I have a cockerel (18 weeks) that has gotten protective of the flock. I had to dust everyone for mites a few weeks ago. And since then this behavior has gotten worse. If I pick up a hen, he will peck the ground a few feet away, picking up random things like dry leaves that he's surely not interested in eating. He gives me the side eye the entire time and slowly circles closer. If I kick my foot out (not even trying to make contact) he'll run away. I afraid to turn my back on him when I have a hen. I try to keep him separated from me when I do. Today when I let everyone out of the coop he gave me the eye as he went by and pecked my shoe softly. I chased him down but couldn't catch him. He also tried to steer me clear of the flock when I was returning this afternoon from the garden. I really don't want to cull him (he's the biggest and nice type) if I can work on his behavior before he outright attacks me. I understand his need to protect the flock but I don't want a people aggressive rooster. Is this a dominance issue? What should I do to try to change his behavior?
