Dinosaur Eggs are dropped by dinosaurs and can be found anywhere a creature decides to drop one. Currently, they can be used as a food source (players can consume them for large amounts of nourishment), for creating Kibble (a useful item for fast and effective Taming), and for hatching (to raise baby dinos; fertilized eggs only).

The ability to hatch fertilized eggs was added in v219.0 through breeding. To mate creatures, you must have a tamed male and female of the same species. They have to be near each and both have to be set on wander or set to mating, not overloaded, not following and not mounted (for mountable dino). A mating bar will appear, and once finished, the female will lay a fertilized egg (differentiated by a red cloud surrounding the egg). Not all creatures can be bred. It is also notable that the creatures have to stay close and the wandering mechanic might drive them apart.

The only exception to fertilized eggs would be the Wyvern, Rock Drake, and Deinonychus, none of which can be tamed in the wild and their fertile eggs must be obtained from the wild nest.

Said eggs spawned in with commands will disappear as soon as they are dropped, and thus can not be hatched. This is due to the egg having little to no health on the command-spawned egg; if it is dropped in an area where it can incubate and the health does not deplete, it can hatch. Any creatures hatched in this manner will always be level 1 due to absence of Maternal and Paternal details.

Eggs all have different colors and sizes while out of the players inventory, and each have a different weight, too. While they are great for kibble production and human consumption, they offer no nutrition to tamed dinos, (except for the Oviraptor, Titanoboa and Basilisk).

Behavior[edit | edit source]

Some dinosaurs will seek you out if you have an egg of their species in your inventory. Any species of herbivore will become aggressive if players pickup an egg from the ground nearby them (except for Dodos, Moschops, and Parasaurs) but simply carrying an egg won't. The Oviraptor has the ability to take eggs without creatures noticing.

  • Raptors, being an aggressive carnivore already, will most assuredly hunt you down.
  • Brontosaurus will also become aggressive if you take an egg near one. But also look out for T-Rex, as they are attracted by Bronto Eggs as well.
  • Giganotosaurus will immediately hunt you down at rapid speed if you take their egg, and being the most dangerous carnivore already known, is a fatal mistake if unprepared.
  • Nearby Wyvern and Rock Drake, usually aggressive at a few distance, will immediately hunt down would-be thieves for taking, or transferring, any of their egg.

Egg Farming[edit | edit source]

Farming eggs efficiently can be very useful to obtain more eggs in a shorter amount of time. Both wild creatures and tamed creatures can be used to build creature farms for eggs.

Frequency and Probability[edit | edit source]

Dodos don't lay eggs like other dinos, every time dodos poop they have a chance to lay an egg.
~ Jen[1]

Only female dinosaurs can lay eggs. Every creature which is capable of laying an egg has exactly the same laying rate (except for Dodos). Currently female dinos will drop eggs continuously, no matter if the player is around or not. (Technically spoken, the creature cannot be in stasis, i.e. the creature has to be loaded which in practice means a player has to be in its vicinity. On the other hand, the game starts the egg laying calculation routine when the creature comes out of stasis, i.e. a player enters the area.)

A mate boosted female has a much higher chance of laying eggs than a non-mate boosted female (2x multiplier). One male can mate boost multiple females of the same species around him, and vice versa.

  • A mate-boosted female creature will have a chance to lay an egg every 17 minutes.
  • An Oviraptor set to wandering provides a buff that reduces the egg laying timer from 17 minutes to 11 minutes 20 seconds.
  • Dodos have different egg laying mechanic: They have a chance of 13% to lay an egg instead of a feces when defecating, which happens randomly after 100 to 300 seconds.
  • There is a limit on how many eggs can be present within a certain range: for most creatures this limit is 6. An exception is Titanoboa which has a limit of 8.

Eggs can also be obtained from wild creatures. Oviraptors can be used to steal eggs from wild or enemy dinos. Whistling "attack my target" on an egg will cause the Oviraptor to pick it up and bring it back to you.

Obtaining Wild Eggs[edit | edit source]

They're pretty rare to find in the wild, it's best to just collect them from your own tames. :)
~ Jen[2]

Mate-Boosted females in the wild that are capable of laying eggs in the wild may drop them, where the egg sits on the ground nearby. These eggs are not fertilized, and cannot be used to hatch a creature. They can, however, be used for kibble and thus are extremely valuable.

If a player approaches and takes the egg into his/her inventory, the animals the egg belongs to(ex: all trikes if trike egg, all raptors if raptor egg) nearby will anger and attack. An Oviraptor can be used to rob the eggs for the player, but then the creature is exposed to the danger of marauding parents. Make sure you can handle the power of the parents if you plan on stealing their eggs!
