I got a couple of Austra White (Australorp X White Leghorn) pullets this last spring. Down was white/yellow with maybe 5-8 randomly-placed little black dots. Adult plumage is a white bird with a few black feathers where the dots were on the down, with black legs also. The white feathers are very lightly peppered with black which isn't noticeable unless you are really close up. One of these pullets has developed gray splotches instead of black. So I'm wondering if I could make something interesting next spring with this bird with crossings. Can I pull the blue (or lavender or whatever) out and make another color of hen to join my little flock? Btw, what is the gray? Is it blue? Is it lavender? Is it something else?
