Please help. What breed are my four chicks and boy or girls?

[nina1marc2]

I am new to chicks. This is a 7 week old chick that I raised from an egg with three other chicks for a life cycle project with my Kindergarten students. I am trying to figure out what breed this chick is and a boy or girl? Anyone know?

This is #2 chick. Breed and boy or girl? Anyone? Also 7weeks.

Pretty sure this is a silkie but going to ask anyways. Boy or girl? Breed? Also 7 weeks

Last one. Breed, boy or girl, and also 7 weeks. Thanks for the help.

They all look like mixed breed pullets to me.

The first one looks like a Partridge Rock pullet.

Thank you both for your help. My students are so curious to what kind of chicks.
