No, the F1s will not have silkie feathering. Breed back to a silkie or to each other for silkie feathering. In the first case, ~50%; in the second, ~25%.

No, breed back to a silkie for 50% silkie feathered offspring. Breeding brothers to sisters will give 25% that are silkie feathered. Of the remaining 75% non-silkie feathered birds, you willl not be able to tell who inherited silkie feathering in one copy and who did not inherit the gene at all. If you select the F1s who are barred, they will supply it to their offspring: fathers to about half their offspring, irrespective of gender, mothers to sons. If you cull F1 females from the program, as Marvin suggests, then you will get barred F2s of both genders. However, barring itself lightens skin; it isn't just Id that is at issue. But getting rid of the Id problem will certainly help.
