Vicious Rooster help please

[Shadrach]

I don't think any are deranged or vicious.. but there is a difference between bravery and stupidity.. don't you think?

I try not to think. I have doubts that I'm fully equipped for the task. I might end up drawing parallels between short men, possibly with an overbearing and domineering wife and rooster behaviour.
I tend to stick to observations and try to base some conclusions on repeatability.
As for bravery and stupidity; well ime experience it's a fine line. Better perhaps to look at it as action and reward. From what I can see from many of the posts on supposedly bad rooster behaviour the roosters are having an easy win. They die the boss and the keeper is one creature less and learn't nothing.

There are very few deranged vicious roosters that attack humans for no reason. It isn't in the interests of their long term health and tbh, one has to admire their bravery if they do.
Even a large rooster isn't likely to weight more than ten percent of the human he attacks. He doesn't have a height advantage or a reach advantage.
From what I've read on this forum in particular the most common reasons for aggression from roosters are, feeding his hens and picking up his hens.
The important point here is, no matter what you may think, the rooster thinks the hens are his.
It's a very important point. For some keepers the inconvenience of coming to terms with the fact that the rooster considers the hens his and expects you to act accordingly is enough to make them decide that there can only be one boss and that has to be the human. I can understand this but in such cases perhaps it's better not to keep roosters.
The next common reason for rooster aggression is that while roosters are juveniles they can be the most affectionate and endearing creatures and their human keeps respond to this treating them more like pets, picking them up, cuddling them and generally making a fuss of them. Unfortunately roosters grow up and their flock status changes along with their behavior. Some keepers cannot adapt to this change.
Imo and in my experience the most sensible advice has been given by cetrarchid and DobieLover and that is wear suitable clothing at all time, much as one would when say handling Mink. A mink is far more aggressive and will happily bite an end of your finger off given the oppertunity. It's your responsibility as a keeper to make sure you dont and nobody else who comes into contact with them gets injured by the animals you keep.
This article may help you understand why your rooster is aggressive towards you. It won't give you a solution to your problem directly though because there are so many variations in your and the roosters behaviour. I have roosters that are absolutely fine if I do A, but not at all impressed if I do B.
It's a long article and there is a lot of information in it. It's up to you to decide which pieces of information are relevant to your keeping arrangements.

Thank you for the link. I read the entire article and found it interesting. Not all relevant as you say - I’m not running multiple flocks nor have such a huge property. I’ve found one part in particular resonates my situation and could be the main antagonist - feeding treats.
the majority of my hens were rescued ex-battery hens and after quarantine and slow introduction they were integrated. Whilst adapting them from caged life to free range I used evening treats to encourage them to bed.There was two reasons for this, one being positive reinforcement of being locked up for the night, the second was trying to put weight/feathers on for the winter.
It became a habit and they wait patiently for me at night. I no longer give the treat directly before bedtime, usually half an hour before so they associate the roosters call to bed and not the treats. I’m guessing to him it doesn’t matter when they get them but the fact that Its me providing “his” hens with treats. I’ve changed tactic as per the article and walked past the hens last night and offered him first then waited til he made the call before giving the rest. I purposefully threw them in front of him and walked away.
whether this makes a difference to his behaviour or not I’ll stick to it as it makes sense in terms of natural order.

Just to annoy, I feed treats and likely have roosters that at least tie for being the most behaved on this whole site. There is more to it, or less to it making for roosters with good behavior.
