thanks village , this is also a email bev sent to me Hi Randy
To get yellow legs you would need two birds that carry the gene for yellow legs to produce a chick with yellow legs. It's my guess that the stock you got from e-bay carried the yellow leg gene. When you saved a rooster from that stock and bred him with his sisters that's when you started seeing the yellow legs.
The second male is carrying the yellow leg gene and so are some of his sisters. If you only breed with the male you got from me and don't do a sibling mating you should be OK. Eventually you will breed the yellow leg gene out.
If you don't understand I'll try and explain it another way.
Kind regards
Bev

The F1 offspring should appear as blue/black, probably with some red leakage, and will dark legs.
I think it would be easier to get a blue wheaten to mix with your Wheatens.
Then again, I may be wrong.....
The lighter shanks will follow the wheaten genes. Your first generation will be hybrid birchen/wheaten or extended black/wheaten, depending on who you got your blues from. I believe most of the good dark egg laying blues out there are birchen based. Birchen is dominant so your chicks should all look like BCM chicks in F1. In your F1 crosses, you will start to see your yellow wheaten chicks again. If your blues and wheatens in the original cross both carried the proper Id shank clearing gene, all your wheaten chicks should still have the good clear shanks.
Id is hard to identify in blues because the blue gene also lightens shanks. So if your Blue was id/id instead of Id/Id then you will get a percentage of gray shanked wheatens as well. But if your original wheaten had correct shanks, they should carry through to at least a portion of the wheaten offspring in F2
Skin color is not sex linked.
Randy,
With 2 out of 25 I would think you only have 1 bird carrying yellow. I wouldn't cull a good hen just because she's paired up with a carrier. Once you identify your pair, take one out and test more eggs. You took all this time to grow out and cull down to just a few good hens (and waited 9 months for them to start laying!), don't be in a hurry to cull a perfectly good bird. I would hatch at least a dozen eggs from each bird. If you have room to do a trio, then you should have room to single mate, it just takes longer. But then you might find the perfect combo that produces killer roos or hens. And then you'll have no regrets about who you're culling.
Recessives don't always play the odds correctly. I was reading about a flock that carried recessive white. And from one season to the next the range of whites thrown was as high as 80% and as low as 1%.
