Much of the information that you wrote there we've tried the culprit was a speckled Sussex was a total ass from day one we would pick him up and carry him around because we read that that would last for about a day and then would have to do it again I stopped doing that because it stopped working and he do it through phases where he'd let you pick them up and pet him and carry them and he was just cool within a month all that changed and the only thing he wanted to do was demand food and spur you if you weren't quick enough about it. I tried a different tactic I kicked him over a fence after he spurred me in the back of my leg while I was going in to get them food then when I faced him he puffed up. Then for good measure as he went squalling around the house the dog chased him for a while insult to injury. That lasted for about 4 days then he would try a different tactic sneaking up from behind instead of being overly aggressive in front of you. I would chase them all over the yard eventually I do catch up with him and I grabbed him by his feet what he didn't like it all and carry him around yard that way for a little bit then I put them down hit walk away and as I turned to walk away he flared up and tried to Spur me again so I drop kick me again that at least lasted for a day 2 days maybe before he started his crap again. The rule with any rooster is if he misbehaves you don't dare run from him that is the beginning of your end cuz he owns you then. Aggression has to be met with aggression so that they understand that there's only one alpha male and he's not it
