What happened?

for both methods to craft a piglich spawn egg in survival, that being mob grinding utils with the mob swab and reliquary with the charms, they either dont drop an egg or are replaced with a chicken egg.
i also found some vindicator varients in the atm mod that craft chicken eggs instead of their actual variants
is this intended or a bug?

Check in JEI if these mobs actually have a spawn egg. Mob Swabs usually always produce a chicken spawn egg if none is available (chicken egg may be the default egg or the first in the table or something)

This isn't really a bug, you're not supposed to be able to get piglich spawn eggs.
