OK, I think I got it! LOL
Here's the whole batch from this set of eggs:
From the left: Catalpa Blue Orp, Cynthia's Something Orp, Cynthia's Blue Orp, Catalpa Blue Orp, in the foreground my Bantam Sultan, and Cynthia's Blue Ameraucana.
Clockwise from top: Cynthia's Blue Ameraucana, the mystery Orp, Catalpa Blue Orp (he has some silvery feathers), Cynthia's Blue Orp, my Sultan, Catalpa Blue Orp.
The two Orps from Cynthia's eggs. The one on the left looks black in comparison, but it's a dark blue.
There might not be very many of them, but the ones I did get are very nice chicks, and seem very healthy. I"m really pleased with the weird coloured one. He looked like an old woman's purple rinsed hair when he hatched.
