Okay, here are three of our nine chicks, now 12 days old. The other six have tiny little wing feathers, or no wings at all (well, little stubbies, anyway.) Actually, the smallest chick in the group is about half the size of the largest...does this mean they are perhaps not the same hatch date? Anyway, back to these three. Does the banding color on the wings of these have anything to do with gender at this age, or is it just different stages of development? Thanks for all the info guys!
