Australorp Chicken , What Gender is it?

[Lemonpie]

Hi I have a 19 week old Australorp. To now he has been suspected as a girl. We think it is a rooster because it fights and tries to mate with our 40 week old hens our hens don't like it and try to avoid him. We have had a rooster before and our girls are over having them! We are most likely getting rid of him if he is a rooster! Here are some photos

He is also a Hy-line show bird. We are yet to put him in competitions because we haven't done competitions before.


Here is the hackle I will upload more but my sister keeps deleting the photos
