I think these are bantams? Don't you just have LF? I had similar juvenile feathering in young blue and black bantams. It went away with the adult molt. I was disappointed in a way because I had hoped they would turn out to be mottleds. Dick said he had some at one point (in bantams).What two breeders, if you don't mind my asking? I've bred blues and blacks since 2008 and have never seen barring on them. I'll agree that a barred something was used somewhere if you are getting barred chicks. Kind of pretty though.
