    F1 will be Black. F2 should be mostly Columbian. I'm no genetics expert but I'm fairly confident that's what you'll get.

    F1s will be Birchen looking just like Black Sex links hens look(black body with gold in breast and hackle), the males will also look birchen in type, There will be no F2 if those F1s are crossed back to Columbian(they are named BC1 as to Back Cross to parent line 1) 50% of those crosses will look Birchen type(just like the F1s and the ones with more silver leakage will be homozygous for Co/Co while being E/eb) and 50% will be Silver Columbian in Type.

    Black Sex link hens are E/eWh, Co/co+, s+/-(your Pullets will be E/eb, Co/co+ S) So your pullets will be very similar but instead of gold they will have Silver/white leakage

    I was totally wrong with the black. @nicalandia would crossing to white be worth a shot?

    It will depend on what the White is hiding, in silkies the white hides partridge, in white rocks is mostly barring and in Ameraucanas is black, recessive white can hide any pattern what determines what is hidding is usually what is the best/most popular pattern breeders are working on the specific breeds.

    My Suggestion is to use black if it has better type than white.

    I didn't really help much but @nicalandia sure did. Hope all goes well with your breeding.
