I've never had friendly chickens before. I have no idea why these ones are friendly, I still treat them all the same. They are TOO friendly though, I don't like it. I want my birds to treat me indifferently. These ones rush up to the house morning, noon and night. We can't get out of the garage without going 1m.p.h. to avoid running them over. They follow me when I'm wandering the property and they've stolen food out of my kids hands. So, how can I nicely make them less friendly?
