Now that you have your incubator, you could buy hatching eggs in rarer breeds that would be too costly buying chicks!
To add to your desire for more feather patterns in your preferred black and white, I can't think of any chicken more beautiful than a well bred Double Laced Silver Barnevelder. K0k0shka had good luck hatching shipped eggs from Blue House Farms. Dark brown, sometimes speckled eggs.
To add to the color of your egg basket, maybe pure bred black Ameraucanas, to give you blue eggs. Or blue Silverudd to give you green.
