I have two cochin chicks that are 3-4 weeks old. I have them in a dog crate and almost every time I open the door to clean or feed they rush over and kick with their feet. They are supposed to be bantams and I don't know if they're boys or girls. This sounds like rooster behavior to me. Would hens do this too? They also dive bomb each other. I have a Silkie chick with them and it just tries to stay out of their way.
