Very true!
However in order for both genders of the offspring to be barred the rooster needs to be barred as well. A hen will pass her barring gene to her sons, but NOT to her daughters (this is the secret of making a black sexlink). A rooster will pass the barring gene to both genders. So I just don't see how a New Hamp-looking rooster can sire these barred babies. I'm baffled.
Very true, and I don't know what's going on with his birds either. I just wanted him to know that even if he crosses true New Hampshire Red roosters with White Rock hens he still may not get Red Sex Links. If he is not mistaken, and has not bred Barred Rock roosters with White Rock hens, then I think the only possible explanation is that his New Hampshire Red roosters (in spite of how they may appear superficially), have some type of barred gene in them. I don't know how to explain that, other than some kind of goof by the hatchery or whoever bred them.
