We have just three hens. I love them a lot because they are funny and they give me eggs. My Barred Rock has been acting aggressively toward us lately. She pecks me when I feed them in the morning and when my DH or our son collects eggs in the evening. Whenever anybody gets close, she pecks, and if we aren't close she comes near to peck. I don't want to get rid of her but since I want my son to be involved in their care, I really need to find a way to stop this behavior.
