Well that is fascinating. I knew you would know the answer - thanks for explaining. You are exactly right both of them have black feathers that are dull. Not even shiny black let alone green!The shine will come after about their 4th juvenile molt. Roughly 4 months or so of age. I do not know what is is about those first few sets of black feathers but they are dull. I wonder if it has something to do as a defensive camouflage method. As a small chick I guess you do not want to be all shiny for a hawk to spot. They are 5 to 6 weeks old now correct? I am very happy to report that I am not spotting any copper feathering at all on Tassels back. Your breeder knew his stuff on correctly guessing her as a pullet.
Yes, they are just over six weeks old. And yes, I am glad he knew what he was about.
