What are the genders of my chicks?

[Zgm12]

Two weeks ago I hatched 8 chicks. I don't think I will keep all of them, so I was wondering based on these photos which ones look most like hens. I know it is impossible to know for sure by just pictures, but I'm open to all opinions.

All of them look like pullets for now, but they're too young to sex accurately.

Agreed.

I just wondered if any looked more like hens than others. I've heard that their feathers can help you tell gender and that hens feather in faster. These are just things that I've heard, though. I'm not very knowledgeable with these types of chickens. I usually stick to silkies.
