Well, here are the facts. One of my RIR chicks feathered out much slower than his sisters, and didn't even get a tail until 5 or 6 weeks of age. I heard that this was characteristic of RIR roosters. His legs were thicker than those of his sisters as well. However, now, at almost 13 weeks, he has almost no comb, which is not that much bigger, if at all bigger, than his sisters'. It is reddish tinged, though, but not vibrant red. Does this show that he is not a rooster? Or are do some just develop late? He has silky, deep red feathers that are different than those of his sisters, and starting to grow in solid green tail feathers. His spurs are not that big yet. No crow, either. What do you think? I'm kind of stumped I'm sorry I don't have good pic, but I'll try to get one if this isn't enough info. Thanks in advance!
