It is theoretically possible, and I suspect this is the case, that the father is recessive white over double barred. Probably a hatchery trick to be able to switch out breeders to produce more barreds or sex links.
If you ask me, he gave 1 copy of barring to all chicks. The chicks with the big, blotchy head spots are definitely males.
