Hello,
I am going to give you my 50% guess, I say it's a girl.
Well, not a girl but not a boy, but not a girl, but then again!!!!
You're guess is as good as mine!!!!
I have a 10 week old EE that up until two weeks ago looked like a hen and then she started crowing and now I am all confused!!!!
I hope the chickie turns out to be whatever you want it to be, but give it lots of love so that if you have to re-home the chicken, s/he will go to people who will love it and not be afraid of being spurred or pecked at.
