Agree with the others....#2 = cockerel, and the other two = pullet.
You're so blessed to own such beauties!

The other two are pullets most likely. Although I did have two cockerels who matured later and had combs like #1 and #3. Then you take into account the rest of the bird, size, legs, etc. Photos of the rest of them would help.
If that's the age of Lav's we are discussing... then there is a GOOD chance they are female.![]()
