100% pullet, her behaviour is just like my light sussex Bella who was hand reared, they show no fear and she often gives me a sharp peck on my ankles or hand or wherever if she is in a mood, usually if I stop her doing something! so don't worry because she is being aggressive it doesn't make her a roo
Hen. I have to say that some of these Polish can confuse you, but it's a hen. Mine pecks my feet or ankles to get my attention to be picked up or for a treat. I think they get into that because it's all they can see. You can trim her bangs and let her see better.
That is a girl. She looks a lot like my pullet, Zarra.
All Polish chickens have tails like that. The real way to tell is the crest. Hens have rounded crests; Roosters have long floppy crests.
