Our Rooster has started charging when you get close to the flock. It is especially bad when we let them out to free range, but he will do it sometimes even in the run. We like having him because we live in a very rural area and helps protect the hens, but being attacked is not fun! Not to mention I have two small boys that I will not let them come in the run with me anymore and they love to feed the chickens! Is there anything we can do to stop him or help with the problem??
