What Subhanalah says is right. There is always so much to learn. I think you will find that most of us have experience or special knowledge in one or a few areas. But who can know everything about everything?
I have several breeds I am quite familiar with, if i'm out of my realm of experience I wait to see what others have to say and try to learn from their experience.
Regarding the "Puffy Cheeks", this is an Ameracauna trait. An easter egger is basically an Ameracauna chicken that does not conform totally to the Ameracauna breed standard, so it is kind of a catch all for non standard chickens that have greenish legs(the green legs is a must). But you don't see a lot of EE chicks with very puffy cheeks, at least not around here. So congrats! Those chickens look great! I love the trait. True Ameracauas are hard to find. I can't find them around here. I would have to travel quite a distance to get some.
