Not related to tea, but I am having a bit of a situation with my cockerel. He is 8 months old and displaying aggressive behavior for a month now. Because he is very short and cute (he's a bantam mix), I have been treating the aggression as a normal hormonal change that all teenagers go through. I deal with him in a way that doesn't trigger aggression and treat him with indifference. If he attacks me, I pick him up and carry him around while doing chicken chores. That is enough for him to stop the aggression for the whole day. I am not aggressive or forceful with him, just matter of fact. DH isn't liking the situation, as he doesn't pick chickens up and has to put a snow shovel in front of him for the roo to stop the attacks. To make matters more complicated for him, the hens don't like him and don't let him near them. He has one brooder buddy (a pullet ) and they are always together, but she doesn't seem to seek his company now as much as he does. He sleeps with her in a dog crate and pecks at her in the morning before they are let out. That's the time he is most angry. I told DH to wait till the weather is warmer and the little guy can go out to forage. Winter is boring for chickens and they might display aggression issues. But that was until yesterday, when DD went inside the run to visit the chickens. The cockerel jumped to her arm when I turned my back. That I didn't like one bit. She wasn't hurt only because she had her winter coat on. Now I am facing with a tough choice to make. Should give him away to a friend that will make nice chicken stew out of him or keep the little guy locked up in a pen? I don't want anybody to get hurt and it looks like his behavior will not improve. I don't want to rehome an aggressive rooster either. It's not fair for the new owners to have to deal with this behavior. But I also believe he has the right to live his life without having to be killed for his behavior, since he wasn't raised for consumption. Decisions, decisions...
Personally, I wouldn't keep a chicken in close confinement, especially by himself. Maybe, I would do it if I could give him a buddy and I really liked him (say for mating or something else to further my chicken plans).
About the aggression, I wouldn't keep an aggressive rooster either. I have three NH roos who are hitting that teenaged stage where they're beginning to try to mate (usually unsuccessfully right now) and one of them (my favorite, the one that couldn't fly out of the coop until a month after the others and who always came up to me and is so so pretty....I digress) anyway, he pecked my boot the other day, so I pushed him with my foot (it was a sturdy I'm ahead of you in the pecking order type of push; it was not a hard or injurous kick). Not five minutes later, he did something to the backs of my legs. I've been attacked by a rooster before and I've been pecked through jeans; it wasn't either one of those things, so I'm guessing he was trying to mate with the backs of my legs. I chased him around trying to push him again, but he evaded me. He behaved the rest of the day, but maybe b/c I kept my eye on him. The next day, he pecked me again and tried to mate with my shoe/leg from the side this time. He got another good push with my boot. I've kept my eye on him, warned the kids (he attacked one of them, minorly, not really an attack, really just a peck, but I told them what to do [stare him down]), and I hope he straightens out. Neither of the other roosters that's maturing is attacking like that. The other two attempt or do dance with me and they try to give me food. I just ignore them (b/c they're not doing anything I don't want them to do, so I treat them with indifference). Bootsy, the aggressive juvenile rooster, may be in my soup pot sooner than later. I won't keep an aggressive rooster. Period.
Ignoring the chicken tells them that you don't mind him/her doing what they're doing. Picking them up shows them that you're the boss. If I had to pick up a rooster everyday to keep him from attacking me or the kids, he'd be in the freezer before he could cluck twice.
Now, that's just me. Everyone has their own way of dealing with these things. There's an article about living with roosters and dealing with unwanted cockerels.
