I got these two hens about 6 months ago. At the time, I had no idea what they were, but they were free, so took them. THe chicks I bought at Tractor Supply. They are about 7 weeks old. First hen: All black with green iridescent feathers on her back. She has a few feathers on her legs. Hen 2: All black with gold on her neck. Feathers on legs. She has odd eyes. They are solid black. This is what I really want to know, These chicks I bought at Tractor Supply. Any idea what they are?
