Last year I bought a couple of Australorp Hens and some Cochins. The Cochin roo bred with the hens and I hatched out some eggs. Today 2 of my new little pullets laid me the prettiest blue-green eggs. Moms lay brown so I am wondering if anyone has an idea of what genetics they may have. Also, one of my little Cochin girls hatched out a very pretty splash Cochin roo.
