Delaware Rooster X Black Orpington hen = 100% barred offspring. No Sex-links.
Reversed: Black Orpington rooster X Delaware hen = Black Barred males, possible Silver leakage. (Headspot at hatch), & solid black females, possible silver leakage.
Well black Orpington X Brown Leghorn won't make...
Same sex linked scenario of the last ones. Also possibility of rose comb.
They'd be sexlinked by shank color as well. Females would be black skinned, & males yellow, or white skinned/shanked.
Eggs would probably be light brown, or tinted.
The chicks may also have walnut combs, if not single, pea, or rose.
Depends if the rooster is pure for pea comb, & also depends if the hen is pure for rose comb.
Yes, they'd be sexlinked. Male Offspring would be black barred, they'd have a headspot at hatch.
(Lavender is recessive, so it won't show in the first generation.)
Female offspring will be solid black.
