I'm supposed to have all girls, as we picked them out in person 2 weeks ago. I was told the BO is supposed to be about 7-8 weeks old. Nice comb coming in there... is it a Buffy, or a Biff? Also, I was told the black one is a Minorca. Can anyone confirm that? He also had Black Australorps for sale but called mine a Black Minorca. She is the same size/age as the BO. Is the Silver Laced Wyandotte, who is supposedly the same age as the BO and the Black whatever, supposed to be so much smaller? She's not much larger than the two Millie Fleur Bantams in there. I'm new to this, can ya tell? In case anyone has ever wondered about this, we built the 3' x 10' mini portable chicken tractor found on motherearthnews. It's pretty sturdy and cost around $150, including the large dog house. We're going to build a second one for the Bantams when they get a little older.
