I have 13 egg laying hens. They are being incredibly aggressive, with humans and with each other (biting, not pecking, the. Faces of my father and I, and flying up to bite us for we are in there). I was wondering if there was anything you guys knew that would help. I gave them a rolling chicken toy from Kaytee. I was wondering if there was anything else. I am renovating the chicken coop this summer so I was just wondering. Any advice would be appreciated.
