I have a flock of 10 chickens with three girls that are 3 months older then the rest. The older chickens are 7 months old and the younger 4 months old. They sleep together in a coop, but otherwise keep to themselves in two groups. Are they ever going to mingle? Also I have only one rooster. He is a Silkie and he is from the younger bunch. Is he ever going to rise in the pecking order? Right now I think he is at the bare bottom, even among the young girls who are mostly EEs. I used to have five more roosters (EEs), but we ate them. Now I worry the lone Silkie won't stand up to his job. Should I have kept one EE roo to protect the girls, or Silkie is going to manage its role?
