Good post Chris as always, you give good information and understanding details.
I have a little tale about this feathering gene(feather sexing). This sex ID method only works if you have bred for it and the feathering of the parent stock is known.
I was on my way thru a little town over in east LA that's (Louisiana, not L.A.) and just happened to stop in a little local feed store there around Easter time to check on feed prices and such. They had an auction there twice monthly and I wanted to see when the next one was to try to unload some chickens there from out of my feed barrel, of course. Well lo and behold they had a big ol' coop full of brand new Barred Rock chicks and many other breeds as well right there handy, and I got to thinking you know I'm getting rid of some chickens and will need some to replace them of course, (light bulbs flashing in my head/dim ones for sure)LOL you know "out with the old in with the new"-(lowering my fed bill right), right!
I inquired about the BRs and she quoted me a price and it wasn't bad and I didn't have to order a washtub full to get some right. So I told her I wanted 10 pullets, she said ok and opened up that coop and went to grabbing up chicks and spreading wings and tossing and grabbing, tossing one here and the other there. This went on for a minute or so and I asked what in the world she was doing a she said: "I'm sexing them" and with an all outta sorts look I'm sure, I asked her: "Ya'll don't have them marked in some way from the hatchery?" she said; "no we order them straight run of the mill and then we divvy them up here per order"(
Making $$ 101 should have been another light bulb moment, a little brighter one right there folks) I should have just stopped right there but I gave her the benefit of the doubt (dummy me)and proceeded to loosen up the ol keister for royal go around. Anyway, I took them, paid her the decided price and placed them in the coop and sure enough in a few weeks (3ish or so) those little dudes started putting on the "most prettiest" pink little 5 pointed combs you ever saw and started feathering in really light grey and bluish hue to their barred little feathers. I ended up with one pullet out of 10 and it was rose combed on top of that (a little factory slip up there huh?) I kept her and one of those boys for a breeder to my other production cuckoos(still have him he makes good egg-layers too) and ate the rest. I didn't ever go back to the place, just couldn't go there cause I'd surely showed my
derriere(that's your @$$ in French for those who don't speak it, common around these parts well with a little southern slang added in there too) I still to this day wonder how many folks fell victim to that little scheme and how much those folks profited over that cage of 500+ little roosters selling them as pullets. "Easter specials" I'm sure, huh? we all know what that one entails usually, well I do now, right around one of our most religious HOLIDAYS in the world. Kinda reminds me of some "CHRISTMAS SPECIALS" too huh?
I never went back and I'm sure they probly lost some business over that ordeal, I, for one would think. Anyway to sum this run-on story up, and I've seen it more than once, actually too many times, folks will say: 'you can feather sex them just by looking at the wing' and most of the time they will follow up with: 'the pullets feathers grow the fastest so they will be the ones with the longer wing feathers or tail feathers'. This is simply
not true in
ALL of the cases, maybe a few. but not ALL (only if they are bred for this trait usually now there are a few breeds this comes into play with, but not the average everyday what-evers)and I'd venture to say you'll be right more than likely half the time (50/50) as they either are a male or a female generally.
