It depends on what they are crossed with. This roo crossed with those Red Sex Link hens gave me a son that looked exactly like him and two that were nearly the same. The roo is by a Salmon Faverolle out of an Ameraucana, hatched from a blue egg. The chicks he sires all have puffy cheeks, heavy lacing. When he mates the Cochin/Ameraucana EE hen, the babies have feathered feet. My other roo is by a Light Brahma out of an Ameraucana, hatched from a blue egg, looks like a Light Brahma except for a small comb and almost no feathers on the shanks, but when he mates the Cochin/Am hen, the babies have 4" long foot feathers!
These are some of my EEs:
