Genetic questions!

Really? So it would look similar to the photo of the Blue Orp x Buff Orp?

Yes

Yes

Awesome!

1. Spangled Sicilian Buttercup x Mottled Ancona:
   • The spangled gene is strong, so most of the chicks will have the spangled pattern. But since mottling is a hidden gene (recessive), some chicks could carry it, but it won’t show unless they get it from both parents.
   • The gold (from the Sicilian Buttercup) and silver (from the Ancona) genes can mix. The male chicks could be “split,” meaning they’ll carry the silver gene but look gold.
2. Cream Legbar Rooster x White Egg-Laying Hen:
   • The blue egg gene is strong, so all the pullets (females) will lay blue eggs.
   • If you breed the F1 pullets back to the original breed rooster, the F2 pullets will still have the blue egg gene and lay blue eggs. They won’t go back to white eggs unless both parents carry the white egg gene.
3. Landrace vs. Heritage Breed:
   • A landrace is a breed that naturally adapts to its environment without much help from humans.
   • Icelandic chickens are a heritage breed, but they have some landrace traits because they were developed in Iceland over a long time. They’re not really "true" landrace because they’ve been selected by humans to keep certain traits.

For the blue egg gene to be passed on to all daughters your original Legbar rooster must actually be homozygous for the blue egg gene. This isn't always so so what happens in practice is only some of them lay blue and others lay white or brown depending on what you bred them too.
