I have a hen who will cut me off as I cross the yard and jump up to peck me. I usually pick her up and hold her upside down while telling her my favorite stew recipe and she behaves for a few days. I feel like I can handle her challenges, but my 2 year old son is terrified to go in the yard! She has gotten him twice from behind. I added a roo to the flock last week and I though he would set her straight, but he hasn't so far. Any suggestions?
