I have black minorca and white faced black spanish. When/how can I tell them apart? (There were langshan too, but I got those sussed out by the leg feathers ) I also have black rosecomb and black sumatra in the mix, can those be told apart yet? I have photos of all of them at 4 days of age, and they are now around 1 week of age. Should I post the pics or is it too early?
