Minecraft cows multiply automatically?

Hi! Today I had an incident on my server with very few cows. After two hours of continuous searching, I found two pieces and my colleagues were able to get a cow for two diamonds (because they were so rare). I had about 8 cows in my base.

Maybe your colleagues have multiplied the cows

Can't be, they would have said that.

Did you ask her?

A "participant" had said that they can multiply automatically.

For sure?

Yes

They can't multiply by themselves, so they must have been propagated
