sex diluted barring, Is it only visible on E^R?

[Spangled]

It's rare? The ones I had segregated out of a line of bantam white naked necks bred for show:

Homozygous cockerel:




Chicks were extremely easy to sex:

Written to Kev and anyone listening.

1) Left chick=female hemizygous B^sd
2) Right chick=male heterozygous B^sd
3) Missing chick=male homozygous B^sd (Would this 3rd chick be solid colored at hatch? Or would this 3rd chicks sometimes be pale gray? Less gray than Left chick above?)

I am surprised that your original naked neck B^sd/B^sd had so much color. Was he I/I? Or I/i+? It seems like more leakage than I would expect. But listen, I'm really inexperienced with chickens. I just imagine a homozygous B^sd to be whiter because I thought that maybe B^sd was more of a white enhancer (or maybe color diluter). If that's a c/c Naked Neck, then I am bamboozled because I would really expect c/c to cover all the gray.

So back to that photo of the two chicks ... my chicks that are now showing some light barring or blue barring (or whatever) did have some of that color of brownish gray (above in your photo, left chick #1) on them which, I thought was really odd when they hatched. Mine were more yellow at that age, but the color of brownish gray is very similar ... I'd say identical, but you know how monitors can vary in their color displays.

I really appreciate your photos and comments. It's all very interesting. B^sd could be a fun gene to play with. Maybe. If it doesn't dilute reds too much. Except what I've got is on ?/E^Wh. I'm guessing that the ? is E^R. I don't want any white chickens or blue chickens, though, so I'm going to have to figure it out on E^Wh or e^b with some E^R thrown in. I am planning on a confusing summer. After all, I don't know if this is blue barring or some sort that is on my chicks and I can't see any barring on any of the darker colored chicks. Plus I need to figure out where blue barring comes from and if that's a possibility for these chicks I have. Blue is a possibility if the rooster is carrying it. The hens I used definitely aren't. I'm still of the persuasion that B^sd is rare as Henk relates. Henk is a genetics phenomenon, genius, and magician. If I ever make it back to Europe, I hope to pay homage by begging him let me take him out for tea, coffee, beer, brownies

, something. I would never be having as much fun with chickens if it weren't for the chicken calculator. Of course, Kev, you've got an Educator badge, too, so you must know what you're talking about, too. So as for "rare" ... ??

Maybe we all have a different definition of "rare." I think of "rare" as in what I heard a book collector describe it as for books ... if you see only one copy in your lifetime as a book collector, it's "rare." Maybe that isn't anyone else's way of looking at "rare." "Hard to find" is another delineation in book collecting, I believe, as is "scarce."
