I have three girls in my original flock. I have since gotten one more, who I am currently trying to acclimate to my other chickens. I have done everything I have been advised to do, to make it an easy transition, and though the newbie still keeps her distance from the others, it is going well. One thing I do notice though is if the newbie is in closed quarters with the others, she ducks her head in a corner, almost reminding me of a flamingo with its head in the sand. I am assuming she is showing her submission in the pecking order, but I want to be sure.
