I wondering also. The hen paired with my smooth feathered rooster produces only smooth feathered birds; pullets at that (I have incubated numerous eggs-many DIS and those that hatch are pullets. Recently I have switched roosters so I'm curious if that will make a difference). Much of what I read on the genetics of frizzle is contradictory or just confusing. If frizzle is recessive the gene has to come from both parents; that much I do know.
Its worth a shot!
