Mine is 6 weeks as well. My granddaughter has decided to call her Elsa the Snow Queen. She looked just like the other "Ameraucauna" babies I bought from tractor supply, although she was more white than tan. Your white one looks pretty similar, but she has the adorable cheek puffs where Elsa is fairly smooth in the face, which is why I was wondering if she was an EE or not. She is getting a little friendlier too, not quite so spazzy. I was going to call her Cleopatra with those eyes, but we already have a cat named Cleo so that wouldn't work LOL
I thought they looked very close in age. Mine are bantams. Well the front one in the pic is supposed to be full sized my other three are bantams. I don't know how my "twins" will deal with the size difference when it happens. Duchess just got renamed for being snooty and a complainer but has suddenly started sitting on my knee or arm to talk to me instead of avoiding me. I'm loving the turn around. She is still quite vocal when concerned about anything though, lol.
I think Elsa suits your girl. How many do you have?
