Hi all, I was so excited to get my shipment of chicks this morning with every single one alive and healthy. I received barred rocks, red stars and pearl white Leghorns along with a free exotic chick which looks to be an EE. The only thing confusing me is there are a few little black spots on a few of the Leghorns. Is this normal? Will the spots go away as they get feathers? I guess I am just wondering if there is a good chance these chicks aren't purebred. None of the leghorns from my last order had them. Regardless, they are cute!
