I bought 4 pullets from a private farmer about a month ago. The chicks were supposedly 2 days old when I bought them. Of the 4 chicks, 3 of them are the same size and one is getting a bright red/orange comb already and the 4th is much smaller than the other 3. The smallest chick seems to keep her head tucked a lot. She doesn't extend her neck when she struts around like the other 3. Do any of my "pullets" look like they may be a roo? Are they still too young to tell? Two are supposed to be Rhodebar and 2 Cinnamon Queen, can anyone distinguish which is which yet? I'll add a picture of them when I first got them and another couple picture if of them now. Any help is greatly appreciated.
