As far as I know, all three of these chickens are mixed breeds. Their sire was said to be a Black Australorp. I believe the dame of the chick in the front (chick 1) was a Buff Brahma, I believe the dame of the one in the middle (chick 2) was a Silver Laced Wyandotte and the dame of the one in the back (chick 3) could be any one of: SLW, BB, English Game, Barred Rock, Leghorn, or Ameraucana. So considering that they are all mixed breed, I would guess that although chick1 and chick2 have dominant characteristics of the BB and the SLW, they won't necessarily fit into the breed standards. I don't know much about chickens but I'm thinking i should be able to be fairly certain that chicks 1 and 2 are cockerels and 3 is a pullet.They are all 11 and a half weeks old with chick1 and chick3 hatching the same day and chick2 hatching the following evening. Any chances I am wrong because keeping roos is, unfortunately, not an option. :/ Also, if it will help I can take close up feather pics tomorrow.
