I got my first Roo recently and he is good around me since I take care of him and his "girls". I went away for the weekend and had my daughter take care of the chickens. Well, he attacked her every time she entered the pen to feed the flock. Do you think he knows me and thinks my daughter was a threat? I didn't think chickens were smart enough to know different people. Should I have my daughter with me for a few times when I feed them so he will get used to her as well?
