Hi, I have an agressive hen. Shes the boss in the coop. I live in the city and can't have roosters. My flock consist of 4 standard size Cochins, 2 silkies, and two sultans. One cochin is very mean as said she is the queen and thus mean to the point that she almost killed one of my sultans. What can I do to calm her down? She pecks, won't let this particular hen eat, and is a bully. If she won't get better I will have to find her a new home. She is a sweet girl to me, but not to the rest of the flock.
