Sorry, your rooster isn't a pure barred rock, and your chicks aren't Delawares. Mixed breed birds can often look like a breed, but they're still mixed breed birds. I have never had a Delaware, but I've had folks swear this bird is one, just poorly colored. She's not, just a mixed bird with barred heritage.

I've also never had an Australorp, but have several black hens from my mixed breeding. I could probably sell them as Aussies, but they're not, they're just mixed breed birds who happen to look like a common breed.
