Most people like 1 rooster per 10 hens. I raise American Games and I have run 1 cock for 30 hens on a free range yard with no problems. Are they in a pen? If so, I would just get one rooster and let him settle the pecking order. If it is free range, then two roosters would suffice. I dont have this luxury with my games, as only one cock will be tolerated. As far as the problem with your son, please dont take this the wrong way. Most problems we have with any animals, we create ourselves. I train horses and dogs and find this to be most prevalent. You have to think like the rooster. Does he feel that you or your son is a threat to himself or his flock?.Chickens are prey more than predator, and their actions are for survival. The rooster may not understand you picking up the hens, gathering eggs , etc.To add to this,you have to factor in his previous environment and personality. Take time to get to know him, and give him space.You will teach one another,and your relationship will be one of mutual respect. I have raised thousands of gamecocks the last 40 years and have only had a handful that were truly just MEAN. I believe they had some sort of mental deficiency. My oldest gamecock was 28 yrs old and we shared some great memories! He got so old he went blind and I would have to put him on the roost pole at night and get him off in the morning. I still have some of his offspring! If you do not have a rooster now and are eating the eggs you are cheating yourself! Fertile eggs are a live cell, therefore better for you. Crack open a egg from the supermarket and you will see they are fertilized. Let me know if I can be of any more assistance.
