For breed:
#1 and #4 might be "Sapphire Olive Eggers"

For #2 and #3, I think they are probably Easter Eggers of some kind (chickens that are supposed to lay blue or green eggs), but I don't know which of these is the most likely fit for each chick:

https://www.hoovershatchery.com/Americana.html
https://www.hoovershatchery.com/prairiebluebellegger.html


For gender:
They may all be pullets.

But #1 and #4 definitely have bigger combs, and #4 has wattles showing a bit of red, so I would keep an eye on them. I would expect males to be more obvious (big red combs), and females to be less obvious (small pale combs) at this age, so those two are in the in-between range where I have trouble making accurate guesses.

Thank you for the links . This helped a lot. I have tried to do some research but they all start to blend together
