Can you tell Chocolate from Dun when they are grown? I have Serama's from Jerry and I am getting brown colored chicks but I don't know if they are dun or chocolate and I can't seem to find anyone who can tell me or show me photo's to tell the difference. I have a young rooster that was a chocolate looking down color but now, he's nearly black feathered and a pullet that was a lighter version of that and she's a beautiful pale coco color, no red tones.
