I have Ameracaunas, and thankfully, they are all hens. They are the sweetest, and want to be picked up and held, and have even wandered in to the house. Yours looks like it has tail feathers of a cockerel, as my girls have very small tail feathers and fluffy butts. Also, we read the articles on how to reform mean cockerels, and followed all the rules, and had to take mighty swings at a couple of roosters. Omg! I knocked one of them out! They still never gave up or gave in, and after all those attempts to train them, they still attacked my granddaughter. Those 2 went to the freezer. The one cockerel that minds his manners goes to the other side of the flock when we come in the yard. Don't wait for someone to get hurt.
