I got 5 chickens from a lady in vermont who advertised them as EE but when we went there, she said that she has purebred birds (and some EE) so there is a chance that some are purebred. she has a lot of Ameraucana, marans, silkies, and i think some barred rock but not many. she also has some game hens/roos but i dont count those when guessing the breed. this girl is much bigger than my others, i believe she is around 20 weeks or so? thats really an estimate though. but no eggs yet so cant say what color she lays. she is all black with muffs (i think) and single comb by the look of it. slate legs but maybe with a slight blue tint? do you think she could be purebred or just another EE?
