I purchased 2 Barnevelder chicks about 5 weeks ago on a limb (went to the feed store to buy food and walked out with 2 new babies. ) however, this is a breed I am excited about but know very little about. Upon coming home and doing some research I am now extremely excited but even more confused. I had no idea how hard they were to sex. And I was dumb enough not to ask how old they were when I purchased them. They had a few rows of feathers on their wings and a few tail feathers so I would guess about a week which would make them about 6 weeks old now. Any guesses as to what sex they are? I noticed one has some green sheen to it’s feathers, maybe a cockril?
