The primary difference between baby and adult hedgehog quills lies in their development and texture. Baby hedgehogs, also known as hoglets, are born with soft, flexible quills that are covered by a thin layer of skin. These quills are not fully developed at birth and begin to harden and become more prominent as the hoglets grow. Typically, the quills start to emerge around 2 to 3 weeks of age, and by the time they are around 6 weeks, they have developed more robust quills.

In contrast, adult hedgehogs have fully developed quills that are stiff and sharp. These quills serve as a defense mechanism against predators. Adult hedgehog quills are also more numerous and can be more varied in color and pattern depending on the breed.

Another notable difference is that baby quills are lighter in color and may appear more translucent compared to the darker, more opaque quills of adult hedgehogs.

Overall, as hedgehogs mature, their quills transition from soft and flexible to stiff and protective, which is a crucial part of their development and survival in the wild.
