This is my 5 week old Mille Fleur. Sometimes, you can tell by attitude almost immediately. When I take photos the roos are consistently standing facing the camera, the hens always seem to hide. I forgot that. With my porcelains, the boys were obvious by 3 weeks because of the combs. I had a terrible time getting her to face the camera. She even jumped down behind the box and the wall.
This is my porcelain from Cackle. He was no where near the prettiest of the boys. I kept him because I re-homed the others to people who were going to breed. He isn't breeding quality and neither were the hens I kept.
