I have six silkies and only one of them has a comb and the others don't seem to. One of the bigger ones seems to be more aggressive then the others. They are 4-5 weeks old. They are just starting to really show their fuzzy feathers on their heads. They are so cute and so sweet. My 7 year old daughter thinks they are ugly but she loves to hold them and love on them. They like her and will follow her threw the house.
