So, I got a White Leghorn...I think

[farmerChef]

leghorns are thin bodied, about 4lbs full grown. my 2yr old leghorn lays huge eggs, they dont even fit in a large egg carton. the eggs will get bigger and more uniform the longer she lays.

Is she pure white?

Assuming it's a leghorn (which it sure looks like it is), they really are much smaller than larger fatter chickens. The first eggs are always small, even for a month or two. And the comb won't flop over for a while. Take a pic of her next to one of your other chickens so we can see the size but my leghorns were about 1/2 the size of my big fat hens (and the eggs ended up being 2x the size quite often).
