Genetic drift is the random fluctuations in allele frequencies due to chance events, and it is more likely to occur in small populations where chance events can have a greater impact. In a large population, random events have less effect on allele frequencies because there is more genetic diversity and more opportunities for gene flow. Therefore, a very small population is more likely to experience genetic drift.
