Flock
Srimad-Bhagavatam
SB Canto 3
SB 3.17.11, Translation and Purport:
O Vidura, the asses ran hither and thither in herds, striking the earth with their hard hooves and wildly braying.
Asses also feel very respectable as a race, and when they run in flocks hither and thither in so-called jollity, it is understood to be a bad sign for human society.
