Both of them have the same sire different mother. One mother suspected ID one suspected id+ and that particular roo being suspected id+/id+. The further test breeding I did on the Sire lead to those being the only logical conclusions. But as I type this, those young roos are now 20 weeks of age and the yellow legged one is being bred back to the parent hens and it's sibling sisters. The results of which should confirm id+ vs ID. Also to try and confirm some other things I'm looking at, not related to id+.
They both at that time were being fed Dumor 20% chick starter.
At the conclusion of this test breeding I'm going to put together a post with as much information as I've learned from it, with visual references and the theories behind it. Before I do that I would like to consult yourself and a couple of other people to see if they feel it's correct. I would also like to get your insights as to other causes in "off colored" shanks and their causes/solutions unrelated to just the genetic side and would like to include that in the final post as well.
Thanks for your time and insights.
Let me know how the test mating go. With two different mothers, it should be easy to see why this is happening. I asked about the feed because some times individual birds will pick out the corn in feed and thus enhance the leg color. That does not seem to be the case here as the chick starter is probably mash. Environment has nothing to do with this case.
Re: my friends white Cornish with the green shank (inside of the shank on only one leg). I found another breeder that had the same thing happen and the leg eventually turned yellow and looked fine. The green was quite dramatic and was really green not green tinged. I have never seen that color green on a birds leg before, so now I know of two casese in one breeding year with different lines in different locations. You never know what you might run into with chickens.

REALLY they are and I am not happy about needing them
