Do I want to learn about genetics? Yes. Is it very intimidating and scary? Yes.

Yes
The Leghorn is still wrong, but if you want to go the whole hog, add IdIdww down ay the bottom to give them yellow legs.
Sometimes it’s hard to know if a breed is dominant white and you have to learn on a case by case basis. White birds with dark legs and chicks are always recessive white. If a breed has a “white-laced red” version or something, the white is probably dominant white. The problem is, some breeds, like Silkies, have both. Then you really can’t know. Extension of black is mainly affected by the e locus but it is also modified by other genes like Columbian, ginger, pattern gene, mahogany and melanic.

Remember to add the crest, feather legs, and rrpp on the Silkie.

What is rrpp?

I am saying adding E^R/E^R makes it black.

Add Db/Db if you want Polish with lacing?

It is a Extended black gene.
