This is my almost 4 month old lavender Wyandotte. We are having trouble deciding if he/she is a rooster because he/she makes a weird noise in the morning, also he/she is pecking and kind of harming the other young hens. No blood or missing feathers. They have been together since they were a day old. So we think if it’s a rooster it wouldn’t harm the hens it would save it’s life for them. Here is a picture tell me what you think.
