Indeed. It seems that what likely occurred is the reverse crossing that Frey's hatchery does and calls "Columbian X" (I think they actually do both and label the sex link version as "Red X" ) where the pullets retain the Columbian pattern and the cockerels appear more of a white brassy leakage typical of sex link style cockerel.Hm.... A white dominant rooster over a red hen does not produce sex links... the other way round does. If you put a red rooster over a white dominant hen you get sex links.
Which if it's the case would indicate all of these are pullets. It's just a little odd how much wattle and comb #30 has compared to the others
