You're the giant that comes to feed and water. If he's aggressive or stupid enough to attack you, then he's not doing his job and being a bad flock master, because he is not watching for actual predators and going after the source of their food and water instead.I could never either, they are just trying to protect themselves or the hens....they just think your a predator. We would applaud them if they attacked a predator but kill them if they mistake us for one. It's not right. If a rooster gets really bad and I can't handle him, he will get a pen for himself and if I can find someone who can take him (knowing he's aggressive) I will rehome, never would I kill him for being a rooster. I may discipline him (not harshly) because I want to try to "fix" him. You should pick up your roosters everytime they come to you, this way they know that if they get to close they get held. If your rooster likes it you may be tripping over him, if not he'll stay away and won't attack
