I have 2 New Hampshire cockerels and 1 Koekoek cockerel. The are 10 weeks old now and starting to fight eachother more aggressively. The one is almost permanently wondering around on his own because the other two keep chasing him off. I was hoping to wait until they were a little older to see how their personalities developed but I don't have space to seperate them and don't like them fighting each other. Now for my question: I want to keep one of the New Hampshires for breeding purposes. When I need to add to my flock or replace birds I can breed him to my Koekoek (a South African breed very similar to Barred Rocks) hens to get sexlinks and don't have to wait for them to grow out before getting rid of the roos. One of the NH is definitely the dominant of the three, but he's also nervous of me and pecks at me if I get too close. He is currently 'top roo' and doing a reasonably good job of protecting his flock (for a 10 week old chick), but I'm worried that as he gets older he will only get more aggressive towards us. He is also considerably darker than the others, so I was wondering if he was really NH or if the breeder accidently put a RIR in with the chicks I ordered. The other one is the lowest in the pecking order of the roos, even the Koekoek beats him and he's half his size. He is however much friendlier and more docile. He also looks more like a NH to me, although I have nothing to compare him too but the hens in the flock and pictures on the internet. As you can see, his tail is a little worse for wear being bullied by the other two. Which is the better example of a NH? And which one would be better in terms of personality? Will the aggressive one calm down when he matures, or become worse? Does the friendly one stand a better chance of being a friendly adult? I have a toddler, cat and rabbits, so I'd prefer a roo that doesn't cause trouble.
