Leghorn?

[Gingerdenae]

Yes, those look like white lobes and the new angle of pics looks like perfect comb size to be a white leghorn pullet. The way you describe her as small compared to the other breeds mentioned is to be expected for her breed. If you look at the bottom of her feet they will likely be yellow, noting her true skin color.

Silkies should have lovely blue lobes, it may be my favorite feature of them. Also from TSC and suspected pullet? Did you already post pics for gender thoughts?

I actually hatched my silkies. I got 3 black, one white and one weird buff colored one with a grey head. They are 12 weeks old and I have no idea the sex. There is one that I suspect is a rooster just by behavior, but they all look the same, lol.
