6 week old (hybrid ?) barred rock. I have two of these chicks. One feathered out a lot sooner than the other, especially the tail. The fast feathering one has a up tail, the slow one in pic has down tail. Other than the tail they are the same color and size. Does this mean anything? I only put pic of slow feathering one on here. They comb doesn’t look reddish in person. It’s more yellow.
