These last couple weeks I have been hatching out eggs from my blue Polish roo over splash hen. I have gotten a couple splash and the rest are blue. However the first two blues were a nice dark blue and the last two have been extremely light blue and when they dry are almost white looking. Will these light blue ones feather out light blue? And why do I get these different shades of blue from the same pair? Just wondering. Light blue chick Dark blue by the food dish.
