Kev, this is my polish nn cross. I have crossed her with many different roos. she is the mom of both the frizzles a couple pages back. I have a genetic question for you. her chicks are almost always the color of the roo. they also have the features of the roo. beard,muff,crest,skin color. Is this unusual?
So you're playing with the NN gene and other genes, that's awesome. Fun isn't it?
As for your question, it probably is coincidence. If the genes your roosters had were dominant genes and/or roo were pure for said genes, that would be the explanation. For example, crest, beard/muff are both dominant genes(actually more like "dominant, but variable in how it shows in the crosses"). This girl lacks the beard/muff so what you're seeing in the case of beard/muffs is more like a "bearded roo x non-bearded hen" cross.. the results would have been overall the same if the sex of parents reversed, non-bearded roo x bearded hen would have produced bearded chicks.
Skin color is slightly trickier because the black skin is dominant but it is affected by unrelated genes(barring, Id<causes white/yellow legs in most non-barred birds>, even some feather colors, etc). In a non complicated cross, black skin x non-black skin will throw black skin chicks no matter what parent is which.
thanks for all the info. I had to read it a few times before it sunk in. I love to play with nn genes.

nope--beginners luck on the original cross. almost every chick was spangled. about half were naked necks. one of the nn chicks also got the appenzeller horns at the top of her comb.
Pic of those? Also happen to have done a 'regular turken' x appenzeller cross? Interested in appearance of Spitz crest on a naked neck... their crest supposedly are different from Polish crests, right? (agree with Lisa that's an exciting cross!)
I sold the last one a couple weeks ago and never thought to take pics. the crest is much smaller and sticks straight up.

Very interesting. Not the same as polish cross crests? Thanks!
He also has white skin(evidence-white legs), not desirable as per the Naked Neck breed standard calling for yellow skin. But if this is not a concern.. if you like him, go for it. He's not pure for the naked neck gene, so half of the offspring will have the same necks as his. Other half will have necks like your pullets'...
I felt a bit sorry for the little speckly chap and had realised he wasn't high quality...The current owner is asking very little for him as he wants him to go to stay alive (!) and in a free range environment....he has started to crow and the neighbours are complaining. He apparently has a very nice temperament, and I'm a sucker for a sob story.(my assorted waifs and strays.....blind sheep, Brahma with twisted spine, runt dog etc. are testament to this.)
I'll have him to ensure his survival and comfort, but will also either hatch another boy from quality eggs or buy a good looker for my girls next Spring.
