Hello, So Im kinda new to this all. I have 8 chickens that are 13 weeks old ( 2 buff orpingtons, 2 ameraucana, 2 australorp and 2 barred rocks) We ended up with one rooster (an australorp) and he keeps attacking one of the ameraucana. I don't know what to do about it. please I could use help on this. Thank you.
