It freaking hurts. I loved this hen, at least I hope she's a hen. I'm new to the chicken world with my 3 hens. They are about 5 months old, with no eggs yet but soon. My R. Island Red has always been the least afraid of people and therefore the most handled and well-liked. But as of 2 weeks ago she has begun to peck at me, leaving marks. I won't go in there yard now without foot protection. I've pushed her back, swatted her when she's pecked at me and generally firmly told her to cut it out. She will still fly up to my lap and doesn't mind being petted, but continues to peck me, stand in my way and chase me. In addition, she has gotten louder than the other chickens doing a "Waa, Waa, Waa!" noise. Any advice?
