I wouldn't worry about the eye stripe at all. That would not be a countersign, given the rest of the birds' pattern. My lost girls had a partial eyestripe. It was taken away in the front of the eyes when the caruncling expanded. But they retained the eye stripe to the rear of the eye. This does NOT appear on the pic of them which you posted..............
It may be that they won't be the best Magpie specimens--in fact that is more likely than not.
Recall that this genotype is highly variable in its phenotype, so some birds have much more color than white, and vice versa. More color, considered a fault of sorts, is the more common thing. Yours, at least so it appears now, will have a relatively large amnt. of color.
But that doesn't make the bird not be a true duclair. Selective breeding is what one may aim for if you are seeking the perfect Magpie.
The eye color of the white types (eg Magpie) will eventually be gray, whereas the eyes of the black types are brown
Also, if the three birds in question have mainly yellow legs and feet, perhaps with some black spots, that is also a good indicator.
But finally, eye stripe or no, I can't see any way of your getting black birds, be they Wild Types or Blacks, from your Magpie looking babies.
Be nice to seem more pics as time goes on.............................................?
good luck this wknd. at the swap
