How long does it take for a rehomed chicken to adjust to their new home and new family? I took one of my 4mo roos, Willie, to his new home on Saturday. From the day he hatched, he's always had a very friendly personality and had never shown me any sort of aggression. So, you can imagine my concern when his new mom sent me a message that he's been attacking her pant legs when she goes into his pen and that he bit her on the lip! THAT is not the boy I raised!! I feel terrible about this! He was such a nice little roo when I gave him to her! Its only been a few days, so we're both hoping that he just needs more time to adjust. Any thoughts on what she can do to help the process? I dont know a whole lot about chicken psychology, but he was the dominant rooster of my flock- could he just be trying to establish dominance with her? Should I have not given him away? Oh dear Bob, I never, in all my life, thought I'd be worrying about the emotional & psychological welfare of a chicken!!! If he continues to be a problem, I am willing to take him back- but what are the odds that this will be a permanent change?
