My pullets have all mixed well, but there is one pullet who is relentless toward the new gals. Has anybody ever tried isolating the bully? She has already drawn blood on one of my pullets. I can see her from the window and she continually charges the new new gals. The other pullets seem to be over it already. They have been mixed for a month and even during free ranging, she seeks them out and charges. Is this just normal behavior? A farmer friend of mine told me to isolate her for six days. What do you think?
