Bird's eggs are occasionally found in bird's nests.
These eggs were first discovered shortly before the release of Farming. These eggs come in three colours; red, green, and blue; identifying with each of the three main gods of RuneScape. Before the release of Summoning their use was unknown.
An egg can be hatched into a pet bird in an incubator (requires level 70 summoning, boosts do not work), or converted using level 63 Spirit cobra's scroll Ophidian Incubation and used in summoning pouches to make any of three trices. It takes about 2-3 hours for the eggs to hatch:
- Green eggs make the Guthix raptor or Guthatrice egg and Spirit guthatrice
- Red eggs make the Zamorak hawk or Zamatrice egg and Spirit zamatrice
- Blue eggs make the Saradomin owl or Saratrice egg and Spirit saratrice
The Guthatrice, Saratrice, and Zamatrice eggs can be sold on the Grand Exchange.
