My Marans are being shipped from Tn. tomarrow and should arrive on thursday. Iam so excited. I will be getting 3 hens and a roo. They are 9 1\\2 weeks old. Will i be able to tell them apart at this age. I am new to this breed and was told that they are pretty much pure Wade Jeane lines, like 96%. Some Cottage Hill would make up the rest. I will post pics when they get here.
