How to many generations to produce lakenvelder color? Using silver columbian Rooster and lakenvelder Hen?

[Tontstee]

I breed my lakenvelder hen to a silver columbian roo and i produce some offsprings but none of them is visual lakenvelder color. Sadly my lakenvelder died and there is no lakenvelder breeder in my area and i want to have that color again.

Do you think inbreeding their offspring might produce a lakenvelder color?

I will attach the picture of their offsprings.

And do they carry the color genes of lakenvelder? Sorry for the noob question coz i am newbie. I want to learn. Thank you so much guys.

Yes, in theory! The main difference between Columbian & Lakenvelder should be just one gene people call charcoal, it's recessive. So your mixed babies each carry one copy of that gene. Breeding them together, in theory, would produce ~half columbian and ~half lakenvelder. However, how exactly the genes express will vary, some may look more "perfect" some may look very wonky with patterning, etc
