Thanks for the link! I think we may end up with black birds. I told my daughter they may end up white or buff; she said it was okay. Anyhow...this is pretty similar to what you have posted as black Sumatras.
Crud. I just now found out not all Sumatra's are black. I ordered them for my daughter from My Pet Chicken. The older they get (they're only 8 days) the more yellow/white they seem to be getting. Any hope of them turning black once they start the ugly stage?
