3 month old white frizzle silkie - rooster?

[Jessicaleigh]

Need some help with this one! I have a 3 month old white frizzle who is definitely mixed with silkie too - she has the 5 toes on her feet. I use "she" lightly because "she" may be a rooster! Here's her history:

I got her and 5 true silkies from a local breeder, but she said she got them from another friend of hers and that the frizzle silkie mix she wasn't sure about the breed. She said they were all the same age but the frizzle was always much bigger than the others from day 1, so I was skeptical.

The frizzle has grown at a similar rate to the other hens and has remained significantly bigger. She started to get some very tall feathers on her head and her face/comb area got very dark pink.

Recently she has started to become a bit aggressive - standing on pieces of wood and perching on things above the other hens. She has started to pick on the smallest hen who seems to be a runt (growing much slower than the rest). This morning I think I heard her crow - she made a very loud sound as she was standing on a stump above the rest of the hens but as soon as I popped around the corner to see who had made the sound she got quiet.

What do you think - do I have a rooster on my hands? Or just an aggressive hen? I can't really tell from the look of her but here is a picture:

I think you have a rooster. See those longer feather starting to grow just before his tail, and the way his tail is starting to get longer, those are both signs of a boy. Its a little hard to tell with the white feathers but you will most likely also find he has long skinny pointy feathers growing on his neck which is another sign.

If you compare the shape and length of the neck feathers (girls have more rounded ends) and those back saddle feathers to those on your girls in the background I think you will find they are very different. It will also tend to hold itself more erect in the way it stands as a boy too.

Are you sure of the sex of the one it's picking on? It may be because it's another boy and he is letting it know it's top rooster.

He's a very pretty boy!
