Leg color sex link?

post #1 of 6
Thread Starter 
In my mixed flock, I crossed a Speckled Sussex roo with an easter egger female. I going to jump the gun and suggest that the males from this cross are darker with dark ish feet, whereas the females are lighter with white feet.

I read up a little on how foot/shank genetics work, but could someone explain how it works for this pairing?

I have some Americaunas that are growing up, if I cover those females with the SS roo, will I see the same effects?

Dark male, feet are colored


Lighter female, white feet


Recent chicks, light left dark right


Corresponding light leg


Corresponding dark ish leg


Thanks for any "feet" back. Hehehe...

I'm not a genetics expert, but I do know that with some breeds, like Barred Rocks, the dark wash on their feet is usually (not 100%, maybe 80%?) indicative of a female. So you certainly could be noticing a valid pattern. However, since your dame is an Easter Egger, which is not a breed, but a hybrid, the (sort of) "sex linked" trait will most likely not carry on to future generations.

I don't think you have sex links.

 

The only leg/shank color sex link I've seen is a black/fm male over a yellow or white shanked female. Females hatch dark, males light.

 

That's what I've read, anyway. I had an accidental clutch of a slate legged Ameraucana over a Dark Cornish and wound up with 3 dark legged cockerels.

Thanks for the input! She's mid molt right now, but when her production starts back up I'm going to hatch some more. Er, for science. :p

With how the green egg laying gene works, these ssxee crosses, will the females lay green/tinted? I'd always thought the green eggs and legs went hand in hand, but I saw on another thread that it wasn't the case.

Well, I don't think your rooster is a Sussex. He's not speckled, and his build doesn't look like a Sussex. His comb looks mixed, so he may have some green egg genes himself, but you wouldn't know for sure unless you bred him to a white egger and saw what color the pullets laid.

 

Going with he's a brown egger, it will depend on what color eggs your EE lay. If they lay blue, then the offspring would lay green. If they lay green, then you'll get a combo of brown and green egger offspring pullets.

 

Leg/shank color and egg color are not at all linked.

 

your two chicks have the same leg color. The darker color down the front is usually referred to as a wash of color, it's not the color of the shanks itself but a kind of overlay.

Oh, those aren't the parents, those are all the F1s! Sire is very much a Speckled Sussex, albeit hatchery stock.

The SS have creme colored eggs, the ee green. Will that produce the same outcome as brownXgreen?

That's cool about the overlay, I didn't know that was a thing! Obviously, ha.

And of course, while I was searching to double check the SS egg color, I stumbled across this blog page which has a SSxEE partial hatch. Looks like a mix of dark and light birds, same goes for the feet from what I can see.
