The board said that I do have black austhrorps, but I was wondering...most of the pics that I see of BAs they have small combs. Mine do not have any..you can barely see a formation of an upside down "V"...are they true black austhrorps? They are 5 1/2 weeks old. I have three of them and one has a smaller tail so i figure its a roo but no comb?
