I'm at a loss on what to do with my 10 month old Amberlink named Della who bites HARD. She doesn't peck, she straight out bites. She was my favorite chick and the friendliest of the 6 but now she is sort of a terror. She just walks up and bites my ankles,my boots, through my pants, my arms, my coat. If I'm sitting she will jump up next to me and bite my arms or jump up on the chair behind me and bite the back of my head and neck. If we are cleaning out the run or coop she supervises and if I turn away I get bit. I thought she wanted attention so I've tried picking her up and carrying her around. I've tried holding her down until she submits. I've tried pecking her back with my fingers and she looks startled but then immediately walks up and bites me again. I don't hand feed treats. They free range during the day and have plenty of room in the coop and enclosed run. Why is she doing this? Is it too late to break her of it?
