I appreciate all your feedback and concern for our children.
I was hoping that perhaps since Moonlight is a teenager, that would justify his behavior and that he would essentially grow out of it. I have been planning on breeding him, however I think the White Face Spanish in him makes him more aggressive. We had his brother too, who was an Amerucauna / White Face Spanish mix that was more aggressive and the two of them would surround hens and mount them while they protested and fought them. They would also trap the children and go after them too.
We also have an American Game Cock that came with the land, who is very respectful of us and keeps a distance only focusing on his girls. Although, that breed is more aggressive due to their fighting history, the previous owners culled roosters that were aggressive (we have found evidence of past roosters in trees and among garden supplies). So, I know breed isn't everything.
Ultimately, we don't have the chickens for pets, we have them as a sustainable food source for our family. Same with our goats. ( We use a spray bottle to control the Billy's behavior while he is in rut. ) So, if there is little hope that Moonlight will grow out of this behavior before his spurs grow in, we won't hesitate to eat him. We still have many Favorelle roosters that I have been watching and one particular one that is quite the gentleman. I also don't want them to learn bad behavior from Moonlight. They already gang raped a poor hen that lost her babies because she left them in the rain.
Chickens are intense.
The big lesson here for the children is that when they chase chicks, those same chicks can grow up to be dangerous, and as much as they may love them, they will loose them.
Lastly, dogs are far more loyal that chickens. We have big dogs who would never hurt our children, even as they age. The only time a dog attacked a child was when my parents rescued a feral sled dog from the mountains. She was quite traumatized having been a work dog that was abandoned and her babies eaten by a mountain lion. I trust my children with our dogs 100%. Roosters on the other hand, not so much. Our dogs don't try to climb the social ladder and fully understand that humans are the alphas whether they are grown or a child.
