We have a small flock of 25 (7 roosters and 18 hens). One of the roosters (I am not sure of the breed but have attached a picture) seems to be dominant along with one other of the same breed. We have a White Leghorn rooster, two Rhode Island Red roosters, a Barred Plymouth Rock rooster and three of this breed in the picture. The one in this picture has been attacking my five and three year-olds when they go out by the chicken house with me and I cannot figure out why. We have had all of these chickens since they were chicks and they are all about 7 months old now. They have free range with plenty of space, food, and water. The attacks started last week where the rooster flaps his wings and gets in the air and scratches the kids' legs with his claws. Of course, now my kids are scared to death to gather eggs or even go to just feed the chickens. Does anyone know why this might be happening? The roosters don't ever show aggression toward me - I don't want this to continue.
