Baby zombies are not spawned when right-clicking onto an adult zombie with a zombie spawn egg

but you can't really "breed" villagers and still spawn them with eggs! so it should be possible with zombies and zombie pigmen too!

"it should be possible" = "feature request"
For feature requests/changes please use the MineCraft Forums: Suggestions

if something doesn't works what used to work you say "it should work but it doesn't" like if a disc wouldn't work then i would say: "The music disc should play music if placed inside a jukebox but it doesn't"
that is NO feature request, it is a report of something what doesn't works!
so it is unfair to close this issue just because i said "should"

I agree with Ali. It would seem reasonable to expect that if right clicking Villagers (a mob that can't be 'bred' by the player) with a spawn egg produces a baby villager, right clicking a Zombie (Villager or Human) would do the same, and create a baby of that species.

now, there ARE baby zombies in survival minecraft, does this still happening? if it is, it should be reopened.

I'd say this is a feature request. Since these mobs cannot breed, they can't produce their baby forms when clicked with an egg. This would be a cool feature though.

Pretty sure this should be reopened as well.

For those that are clearly not understanding the situation, whether the mob is bred by the player or not is negligible, the fact remains that the mobs still breed in some form. Zombies and zombie pigmen do not breed under any circumstances however, so the reason for spawn eggs not having the desired effect still stands.

Still affecting 19w13b, I fail to see how this very obvious inconsistency has not been reopened yet.

Presumably, zombies do not bear children, and baby zombies are instead the result of infection. Whether or not the player can breed the mobs is irrelevant – the question is how the babies are produced.

Baby zombie and skeleton horses can be spawned through the spawn egg method, though, and can't breed, implying these are also only available through infection.
