Sexing my Sizzle Showgirl chicks

[Silkiechickie13]

I have one more question, will the one that might be a hen fill out a little more? Usually my hens have a nicer crest than my males but it flipped around this time lol. The two bigger ones (partdrige and larger paint) have very nice feathering and are a lot typier than the other chicks I sold that looked like hens. I originally had 5.
