Just read your post. I have a Buff Orpington hen named Amanda who DEMANDS to be held. We know when she wants to be picked up because she will come over and peck you to get your attention. If you do not pay attention to her or pick her up, she will then bite you. At first we thought this behavior meant that she wanted/expected food from us. We'd offer her bread, corn, etc, and she'd ignore the food and continue with the pecking and biting behavior. She is fine and relaxes when we pick her up, but the pecking/biting behavior resumes once we put her down. Amanda is going to be 6 years old in July 2015 and her behavior has not changed. She is a pet and we have accepted that she thinks she is a diva and we treat her like one. Too funny!
