Try "platypus."

I hope this helps. Thanks for asking.

To determine what animal fits this description, we can break down the characteristics mentioned and analyze each one individually.

1. "I have a bill like a duck": This indicates that the animal has a bill or beak similar to that of a duck. Ducks belong to a group of birds known as waterfowl, characterized by their distinct bills.

2. "The hair of a mammal": Most mammals have fur or hair on their bodies. This suggests that this particular animal has hair like a mammal, rather than feathers like a bird.

3. "I lay eggs like a bird": This implies that the animal reproduces by laying eggs, similar to birds. Unlike mammals that give birth to live young, birds lay eggs to reproduce.

4. "But I nurse my young": This means that the animal provides nourishment or care to its offspring after hatching from the eggs. Nursing typically refers to the act of breastfeeding, which is commonly observed among mammals.

Combining these characteristics, the animal that fits this description is the platypus. The platypus has a duck-like bill, possesses fur on its body, lays eggs like a bird, and nurses its young with milk.

In summary, based on the traits mentioned, the animal in question is the platypus.
