What breed is this?

[Sunny the Chicken]

What breed is this? She's a hen, around 20 weeks old, pretty slim but not underweight. Hasn't started laying yet. I think she's at the bottom of the pecking order. Unlike her friends she still talks in really high pitched squeaks. She hates being held, but isn't afraid to be near me. Wattles and comb are really small and pale compared to everyone else in the flock.

I have another leghorn though (I think), and her comb and wattles are giant and extremely red

She could be a he, or maybe just have larger comb and wattles post pictures if you want help determining sex/breed of the other one

May be a cockerel or just very close to Point of lay.

I definitely only have one cockerel that crows all day long, and he hunts down all the others in an attempt to mate. I'm 100% sure he's the only one

Then the other leghorn is probably really close to laying!

Do you have any photos?
And, are you sure the pullet in question is 20 weeks? She doesn't look it.
