Eggs are laid by creatures with the LAYS_EGGS token. This includes ordinary fowl and reptiles, and also some more exotic creatures such as giant eagles, dragons, kobolds, and many others. Eggs can be used by dwarves as food, or they can be hatched. Eggs can only be eaten raw if at least one of their component materials (yolk, white, or shell) is edible raw; otherwise, they have to be cooked into prepared meals first.

Egg laying animals will claim an empty Nest box if one is available.

Males can also be modded to lay eggs, although these may not hatch.^{Needs clarification}

Hatching Conditions

Hatching eggs requires that the dwarves are prevented from removing the eggs (and mother) from the nest box until they have a chance to hatch. This can be done by placing the nest box behind a locked door or by forbidding the eggs in the nest box. Forbidding eggs on the kitchen menu will not prevent dwarves from removing them from the nest box — it will only prevent them from being cooked. Similarly, modifying all stockpiles to disallow eggs will prevent hauling jobs, however the eggs remain available for cooking and eating.

Eggs may be fertilized when laid, or they may not. In order for eggs to be fertilized, a male of the species must be present (though this does not always guarantee fertilization). Depending on the animal, fertilization chances seem to differ. ^[Verify] If the creature is part of an actual civilization, then the egg-laying female must also be married in order for her eggs to be fertilized, and she likely must also be able to path to her husband. (In short, egg fertilization has the same conditions as normal impregnation in the game.)

All fertilized eggs left undisturbed in a nest box hatch after exactly 3 months, unlike in real life.

Egg Production

Fortresses can set up egg production as a source of food. This requires at least one adult, tame, female egg-laying animal, a built and unclaimed nest box, food hauling, and cooking.

Egg Composition

It appears from tests that the material an egg is made out of is actually the shell; this includes meals made from the eggs.
