I got an order of chicks the other day from ideal poultry and it came with nine of these black chicks added for warmth. I don't think they are a barred variety because they are all black and have no white spots on their head. I was thinking they might be black australorp males because that's the only black layer I can think of that isn't uncommon. So what do you think? Any other types of black layer birds that a hatchery would likely have surpluss of? Thanks!
