Right. There have been clues in other discussions using words such as "too naked" so I was going with that. I think in some cases, the advise is partly due to having a personal taste of finding the NaNa showgirls "ugly".
NaNa P? can be extremely naked, far more naked than the usual NaNa with single comb. At hatching an extreme case can appear nearly completely naked save for a pencil thin line of fuzz down the back, sparse fuzz on wings and only a small spot of fuzz on the thigh, the cap is reduced to half of the usual cap size(if chick has large head knob, the naked area can extend halfway up front of knob and extend along the bottom more than halfway- it really looks like a bad case of receding hairline on a human), etc. It appeared some people took this amount of naked-ness as being due to too much naked neck-naked neck breeding when they were merely seeing the effects of a homozygous Na with pea comb. No idea if there's also a dosage effect between NaNa Pp+ vs. NaNaPP... kind of wonder if the "extremely naked" chicks with barely any down on wings, legs etc may have been PP.. have hatched a few of those out of a mongrel stock, but didn't keep or test mate those to figure out their genotype.. but for a naked neck chick to have sparse down on wings is pretty extreme, as this doesn't happen with single combed birds, even if they are otherwise "pretty naked".
When I first learned of the P effect, I deliberately inbred a pure OEG hen with Pp+ comb genotype with a naked necked rooster and bred a single combed naked neck son each generation back to her for.. I forgot how many times, it was either 4 or 5 generations.. until the chicks were pretty much clones of each other in appearence. Every time, there was a visible difference in the nakedness between Pp+ and p+p+ chicks- the former had small bowties, naked space between eye and beak, naked space behind eye and cap, while the latter had "fully fuzzy" faces with no naked spaces and the bowtie was the usual much bigger patch etc. Nearly took it a step further by breeding a Pp+ Nana son with her with the intent to create NaNaPP to see if they looked any different.. but got burned out by too may projects, too many birds and culled them out.
