I know/see that this is an old post. WE had very nasty roosters last year (our first year). By this time, we had given away and culled every rooster. Of course, we got more chicks this year, so we get more roosters. But this year, even with some being hatchery, our roosters are all the gentlemen. They were raised the same. They are pleasant sweet, don't look twice at the humans (including my two boys 6 and 7 years old).
Over and over again, my husband has said, "we will never put up with roosters like we did last year." He got his head scratched by a measly one pound golden sebright boy. We had lt brahmas poorly behaved attacking the pullets in groups. We had scratches down our legs constantly. That is until they were gone. I debated how to do it and finally decided humanely and to benefit from the meat. So, we did. Still was hard, so don't read in to it that we enjoyed it. Took me a long time to get used to the fact that it was necessary.
But this year, we were prepared, would have culled at the first sign of nastiness (we were too new last year, still looked at these guys like pets -- they are not a cat or dog, they are chickens). I am telling you, we will never let that happen again. My goodness, our boys are respectful, call to the ladies to get treats they find, do the wing dip to impress the ladies, and generally make themselves useful. We have a large flock (as we did last year) and they all have groups that they hang in (usually groups of 4-5 together with one rooster).
Anyway, point is, don't let a rooster ruin your experience with the chickens, we did, we regret it, and didn't realize how nice it was with no roosters, or even better - with well behaved roosters. Good luck. It's hard, my better half reminds me that it is part of farming/animal husbandry and it's certainly not the nicest one.
