The leg-feathering and pea comb will be split, which means the offspring will have one leg-feathering gene and one not leg-feathering gene and one pea and one not-pea gene.
The feathered legs are dominant so the offspring should have featherd legs.
Pea comb is dominant so they should have a pea comb. However when they are split like this with one pea comb gene and one not-pea comb gene you often get a wonky looking comb, sort of between pea and single. I had an EE like that once.
The pullets will not be barred and the cockerels will be split for barring. Since barring is dominant it will show up, but since the male will be white, you'll only see the barring in the tail and probably hackle feathers. It will be there in the white, you just won't be able to see it.
So your roosters should look like a Delaware rooster except with feathered legs and probably a wonky half-pea comb. Your pullets should look like light Brahma hens, though maybe with a wonky comb.
Exactly as Big Medicine said, egg laying abitlity will depend on the parent's egg laying ability.
