I'm slightly confused, I thought OP only had female silkies. Wouldn't a silkied×normal feather produce heterozygous silkied, and thus normal feathered birds carrying the silkied feather gene?
I do not. Possibly some frizzles in there, maybe crests, leg feathering, and 5 toes, if the silkies and silkie mixes have five toes. I do see one girl with a rose comb, so you might have some heterozygous rose combs, although you say she isn't laying, so not very likely. Natj will be much more...
