Unsure of Breed and Gender

[jmonday]

We are new to the realm of chickens. We have 3 chickens we have had since hatching them 13 weeks ago. The gender of Sweets and Roo seem obvious plus Roo recently began crowing. However Chessy is a mystery. At times we think she is a hen then we question that. I have uploaded pics of all our chickens in hopes for some guidance of types and gender they are.
The 1st and last image is of Chessy. The 2nd and 3rd are of Roo. Thanks a bunch.

I only posted pics of two chicken, just different views of them. The one (Chessy) on the black tub is the same chicken in the 1st image. At times we think (she) is a he because of the size of the body, comb, and waddle. However, we are not sure of her breed and hens can have larger combs, ect. We are not sure of the breeds. The eggs (these chickens) before they hatched were blue and some were light brown. The person we got the eggs from (this was a class incubation project) said they were either orpingtons, americanas, or partridge rocks. Any ideas. Thank you for the imput thus far!

middle one is an ee the other one ummm looks like a mix with orp (im guessing orp/rock mix) body type is wrong for a pure orp

this one is a Buff Columbian orp

We figured the middle one was an ee based on it's coloring-thank you. I had done some research on orpingtons and rocks and your response helps confirm what we have thought.
