Yes.

Normal Cock = ZZ
Opaline Hen = ZoWZoW

Offspring Phenotype Results:
Males: 100% Normal
Females: 100% Normal

Offspring Genotype Results:
50% Male split for opaline (ZZo)
50% Female normal (ZW)

If he is opaline, all of the females will be opaline, and so will all of the males. Is that correct?
Yes.

Opaline Cock = ZoZo
Opaline Hen = ZoWZoW
ZoZo x ZoWZoW = 50% ZoZo (opaline males) + 50% ZoWZoW (opaline females)
