Those birds (especially the big, red roo) are beautiful!
I had a hatch of mixed orpingtons (the lady I got the eggs from had only orpingtons---black, lavender, buff, etc.) on July 1. One of the chicks looks like a huge, fluffy robin, and another looks like it has yellow/red and blue barring on it's face and head, and then blue/black/ white barring on its body. I don't know how that can be if the birds were pure, but I guess the originals might have been from a hatchery with some degree of mix to them. Interesting to see these pictures.
