These two chicks are from the same parents. The hen is a commercial hatchery "amaracauna" and the rooster is mixed Cochin/RIR. The blue chick has clean blue feet. The other chick has yellow feet with a tinge of blue. And feathered shanks. It also appears rumpless but if you feel it it does have a tail sort of. Anyone have any input on why they turned out this way??
