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.

Some dinosaurs will seek you out if you have an egg of their species in your inventory. While they are great for kibble production and human consumption, they offer no nutrition to tamed dinos, (except for the Oviraptor, Titanoboa and Basilisk). Any creatures hatched in this manner will always be level 1 due to absence of Maternal and Paternal details.Įggs all have different colors and sizes while out of the players inventory, and each have a different weight, too. 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. Said eggs spawned in with commands will disappear as soon as they are dropped, and thus can not be hatched. The only exception to fertilized eggs would be the Wyvern, Rock Drake, Deinonychus, and Magmasaur, none of which can be tamed in the wild and their fertile eggs must be obtained from the wild nest. It is also notable that the creatures have to stay close and the wandering mechanic might drive them apart. A mating bar will appear, and once finished, the female will lay a fertilized egg (differentiated by a red cloud surrounding the egg). 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). To mate creatures, you must have a tamed male and female of the same species. The ability to hatch fertilized eggs was added in v219.0 through breeding. 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 creatures fertilized eggs only).

Eggs are dropped by certain creatures and can be found anywhere they decide to drop one.
