Asksvin eggs are laid by Asksvin in the Ashlands biome. See Asksvin - Breeding for more details.
Hatching[]
When placed near a fire or heat source and under a roof (needs shelter) for 30 minutes, the egg will hatch and an Asksvin hatchling will spawn, which will then grow into an adult Asksvin. The egg must be individual - not in a stack - in order to hatch.
Unlike chicken eggs, Asksvin eggs come in different qualities. The number (quality) at the top right of the icon notes the level (stars) of the hatchling:
Quality "1" hatches into regular Askvin hatchlings
Quality "2" hatches into 1-star Askvin hatchlings
Quality "3" hatches into 2-star Askvin hatchlings.
