I hatched some eggs from a guy on craigslist. He had a lot of breeds in different pens. I hatched blue and brown eggs. These babies all hatched at the same time, I dont know who came from what egg. The breeder said he was developing F1 olive eggers. I think he was using cream legbars for this experiment. DH picked up the eggs for me and didn't get any info. So now I have these 5 black/barred chicks with feathered feet. They are 12 days old. Any idea on breed?
