I really don't know, because I just purchased my Silkies, but was told when selecting them that the bigger the knot on the silkies head the better the comb will be. The two I picked with the bigger knots have fuller bigger combs. The one my daughter picked without a knot has a single comb. So...
We managed to end up with three on a trip to first Monday today. We only pray one will be a girl. That being said let our journey begin. Thank you for your help and if by chance these turn out not to be what we were wanting it is good to know I can contact you!
