I’m somewhat new to minecraft and was messing around with the spawn eggs, I had 64 pillager eggs in my pocket (along with many other kinds) and I dropped them to make room in my pocket. A few minutes later I had to kill what felt like at least 50 pillagers, do the eggs spawn on their own when they are dropped? There is not an outpost near by so there’s no way they would have spawned without an egg.
If you're in a village you might have triggered a raid, if you killed a pillager with a banner and got the Bad Omen effect but I think that should spawn new waves until you've defeated the raid whether it's night or day.
There’s no raid bar! The house I built is by a village but I’ve been in a raid before and this is nothing like that, they’re completely non-hostile and spawn Roughly 10 at a time and every time I kill them all they spawn again until morning time.
