Opinions on these 6.... Cockerel or Pullets?

[Jgerrior125]

Hello. Here are 6 of the 8 new chicks we adopted from my sons classroom. I am still waiting for more information from the teacher regarding the breeds of the black ones but we have 1 zombie and 1 barred rock. 2 not pictured are Cream legbar but was told they were auto sexed so know those are at least pullets. These are 6-7 week old so would love to hear your guesses. And also any information/tips on the feathers growing on #5s legs?
Hoping for some luck as we just found out the first group of chickens we got 2,/4 were cockerels and maybe even a 3rd one so we are not doing so good here.

I see no obvious cockerels at the moment.
