I also got these from Dunlap hatchery. They are all Black Australorps. I don't have a recent picture of my rooster. When I get a good picture I'll post it.
I don't know what BCM means. Usually with genes, darkest colors are dominant. Black will almost always show. Until white is introduced. White tends to be at least co dominant. Which means both white and another color will show. If you were to breed a Black Australorp to say a White Leghorn you'll probably get a White chicken that may possible have some black on them. In some species of animals red and black are co dominant as well.
Thank you! Those look cool. The only Marans that I can find with ease is the Cuckoo Marans from Dunlap Hatchery. BA are my favorite. They are hardy, very calm and friendly, amazing egg layers, lay for a long time, and can make great meat birds too. I use my hens for eggs. Any roosters I hatch out become broilers.
Hopefully this spring I will be able to hatch out some White peachicks and sell them. It mainly depends on my White peacock and how many eggs my hens will lay.
