As usual, I’m late to the party, but I’ll share my opinion anyway. I agree with Sourland. Your “rooster” is actually an immature cockerel, full of hormones and his behavior needs to be nipped. When my cockerels are old enough for me to know that they are cockerels, I stop handling them. I move with confidence when I’m around them. I walk through them to get where I want to be. I keep an eye on them and if one starts to move aggressively toward me, I will walk towards that bird and back him up. Sometimes I will just move them away from the food or water because I can. I don’t turn my back on them when they start feeling their oats. When I do get to that point, I don’t fully trust them at first. If one sneaks up behind me, I will turn around and walk toward it - again, making him move. I have not had a human aggressive rooster since I started raising them that way. He is not in charge, and he respects my space. I will not keep a rooster who is too stupid to figure out that I am not a predator. If he’s busy stalking me, he’s not doing his job.
