Pullet or Cockerel?

[sunnyside724]

I have 4 EE's that are 9 weeks. I am beginning to think 3 are cockerel's and one a pullet. I'm new to this, help! lol
I did hear a crow this morning but google says sometimes hens can crow. So now I'm just more confused.

You are right. The one brown one that's showing only her tail in the first pic is the pullet.

The lighter grey one and the brown one with the black tail are cockerels. The brown partridge one is a pullet. I’m also leaning towards pullet on the darker grey one, but don’t feel sure.

Crowing hens are unusual and more likely with older hens. At this age, crowing almost certainly indicates boy.

The dark grey one Im unsure of too, my only indication that its probably a roo is its a little aggressive. Yesterday while giving treats it was only pecking at my hand. Going around the treat to peck me and then tried to peck my face. So im going to have to watch that one.
