There are some Easter Eggers with no muffs.
I don't seriously think they are Easter Eggers, just pointing out that "no muffs" is not proof of "not Easter Egger."
Probably both Buffs are Chanteclers.
Due to how the comb genetics work, it is possible for some Chanteclers to produce chicks with pea combs, even when the parents have the correct cushion combs. (It involves the same genes that let some rose comb Wyandottes produce single comb chicks.)
If one...
