Worried My BO/Ameri Cross is a Boy

[Danniro]

Her comb (can't tell if it's pea comb or single comb) is a bright pink but still quite small. Her and her half sister (who is jersey giant/BO) are both 10 weeks. The Ameri/BO is quite a bit smaller than her sister, but also is slimmer. She is not as fluffy and full looking which worries me because I was expecting them both to be fairly large and fluffy. Her tail feathers are pointy but her saddle feathers look rounded. I don't know if her behavior has been rooster-like though a couple times when I reached for her she pecked me lightly and her sisterr has never done that. But the JG/BO is calmer than her sister.
Uh, what happened to where you can upload photos? I'll put Flickr links.

I'm leaning towards cockerel.

I'm thinking pullet for now, but I am not 100% sure.

I'm also going to say pullet.... But it's a tough call.

Oh man, sounds like I'm just going to have to wait...
