However, donkeys do have distinct life stages:
1. Foal (0-1 year old): A newborn donkey is called a foal. They are dependent on their mother for milk and protection. They develop quickly, learning to walk, eat solid food, and interact with other donkeys.
2. Yearling (1-2 years old): A yearling donkey continues to grow and mature. They start to develop their full size and strength. They may be weaned from their mother around this time.
3. Juvenile (2-4 years old): By now, donkeys have reached almost full size. They are becoming more independent and learning social skills. They might start to develop a "herd" mentality.
4. Adult (4 years and up): Donkeys reach sexual maturity around 2-3 years old. They are considered full adults by the age of four. They can now reproduce and take on the responsibilities of raising young.
5. Senior (15+ years old): Just like humans, donkeys can live for a long time. Once they reach the age of 15, they are considered seniors. While their physical abilities may decline, they can still live full lives and be valuable members of their herd.
Note: The age ranges given above are approximate and can vary slightly depending on breed, environment, and other factors.
