Hi Jayne. Sorry for the delayed reply.
I did a bit of research but couldn't find any Brahmas listed as rare breeds but that may be my poor research skills. I have no personal experience of the breed.
As regards my own cocks/cockerels, I have 2 cream legbars , 2 welsummers, 3 exchequer leghorns, one brown leghorn cross, 5 marans crosses and 5 legbar crosses and 5 farmyard mutt youngsters that are about 10 weeks .... I hadn't actually totalled them up until now that you've asked about them and it's worse than I thought....as I said..... far too many and some will be getting processed tomorrow night as they are making a nuisance of themselves with the girls. Having an established head cock bird helps to keep the junior males in check as regards aggressive behaviour.... it's just raging hormones causing them to grab any hen or pullet they can sneak up on. My bachelor pad is already full, so the ones still within the flock that are causing a nuisance will have to go first. They have had a much better and longer life than supermarket shelf chickens, so whilst it is emotionally very hard for me to process them, I can at least ease my conscience that they had the best life possible..
Harry my original legbar, who is head honcho was very well behaved towards me when I first got him but extremely aggressive towards Horace my original exchequer leghorn. Eventually I had to move Horace and his ladies to a separate area as he was really getting a daily hammering from Harry. The moment Horace was out of the picture, Harry decided to have a go at me. We had two or 3 weeks of dispute over this until he accepted I'm the boss and since then he's been good as gold and not aggressive towards me or anyone else or any of the other cockerels that have grown up in the flock, many of which have been his sons.
Interestingly, after I moved him, Horace, who had never been a problem, decided to challenge me too on a daily basis and I was never able to train him and had to keep a broom handy at all times in his presence. He was the one that took on a dog and lost and I was not as sad as I might otherwise have been. So, the more dominant of the two was trainable and we now have mutual respect but the lower ranking one, once he had his own area and girls, would attack me the minute he got the chance.
I now have Harry and Henry (Henry is no trouble at all) as my two flock cocks and the youngsters are all surplus cross breeds that get raised to about 6 months for meat. Once they start harassing the girls it helps to motivate me to deal with them..
How are things going with your laddo? Do you think you are making any progress with his manners?
