White Dorking

[Of the Glenn]

Is it possible to get a White Dorking by crossing a Silver Gray with a rose comb White Leghorn and then crossing back to Silver Grey culling for White Dorking SOP?

Theoretically yes, but leghorns are dominant white and hide other colors below that top coat

That is a terrible idea. I can't think of a worse white bird to use to this end.

White dorkings exist. They're not easy to find, but it'd be cheaper, quicker and easier to take a decade to find them than it would be to use a leghorn to try to recreate them.
