I'm sorry if I get them mixed up. I know that is a no no. I'm new to the silkie world. This is my first go at silkies and chickens period. I've only had them since June of this year. I'm learning very slowly. I have learned that I can't hatch silkies. I've tried several times and failed hence, the hatchery chicks. I was successful at hatching several other LF and bantams, but not silkies. Thankfully, I have found lots of information on this site.A crest does not require a vaulted skull. THey are entirely separate things.
