I was playing survival and I threw some eggs for my farm, one egg spawned 4 chickens, threw 3 more eggs, one of them got 4 more chickens, so i threw a few more just to see and 2 of those eggs spawned 4 chickens each. The statistics that I just got so lucky is so improbable, so it must be a bug. I tried to record after all that happened, but I never got it again.
It’s not necessarily a bug, though those are extremely lucky odds. Although I don’t see how it’s a bug if it didn’t happen again. If it isn’t a constant problem then it probably was just that you got incredibly lucky.
