Hedgehogs typically start quilling at around 3 to 4 weeks of age. Quilling is the process where baby hedgehogs shed their baby quills and grow in adult quills, which can be a bit uncomfortable for them. During this time, you may notice that your hedgehog is more irritable and may not want to be handled as much. It's important to provide a comfortable environment with plenty of hiding spots and soft bedding to help them through this transition. The quilling process can last until they're about 6 months old, so be patient and gentle with your little spiky friend during this time. Proper nutrition and hydration are also crucial to support their growth and development during quilling.
