I also have two barred EE's that don't have muffs. And if you look at her legs, they do have a greenish sheen down the front. Here's my girl "Fuzz", with a muff, and my two barred EE pullets with no muffs.
Thanks for giving me some hope that we've got more pullets than roosters! The dark chicken is my favorite and I'm happy about the possibility that it's a girl, but I'm still worried about the white one.
I have some older EEs that were muffless at 6 weeks, and then, 4 or 5 weeks later, they grew in Santa Claus beards! It was quite a pleasant surprise.
