I have 4 silkie babies a little more than 2 weeks old. One has a very wide comb 'area' although it's still completely smooth with no evidence of any bumps. The other 3 have very narrow combs. Could this be an indication of a rooster? The width is very similar, proportionally, to the OP's picture in the 1st post. The baby is, also, bigger and has a lot more feathers on the legs than the other 3. I guess pics would help, huh? We were just watching them and we noticed all of these things.
