A '''nest box''' is a 1x1 building that, once created and placed, a tame, [[egg]]-laying creature will claim and use to lay eggs in.

A nest box is created using a single piece of [[wood]] or [[stone]] at a [[craftsdwarf's workshop]], a single bag of [[sand]] (and optional crystal/pearlash) at a [[glass furnace]] or [[magma glass furnace]], or a single bar of [[metal]] at a [[metalsmith's forge]] or [[magma forge]]. Unplaced nest boxes are stored in the [[tool]] section of a finished goods [[stockpile]].

* To create one at a Craftdwarf's workshop, {{K|q}}uery the workshop, select {{K|w}}ood products, then use {{K|+}}/{{K|-}} to manually highlight "Make wooden Nest Box", or select {{K|g}} rock products, then use {{K|+}}/{{K|-}} to manually highlight "Make rock Nest Box".

* For a glass nest box, {{K|q}}uery the workshop, select {{K|g}}reen/{{K|c}}lear/{{K|k}} crystal glass, then use {{K|+}}/{{K|-}} to manually highlight "Make ''type'' glass Nest Box".

Once created, the nest box is then {{k|b}}uilt using {{K|Shift}} + {{K|n}} and will not block movement. The box will then be claimed by an egg laying animal when it is ready to lay eggs. The animal that claims the nest box will periodically lay [[egg]]s into the nest. This process is very quick (<1 day) and the eggs are ready to be collected immediately if they are to be cooked, but require time to hatch if you wish to start a breeding program.

If dwarves have access to the nest, a dwarf with the [[food hauling]] labor enabled will then remove the eggs and take them to a food stockpile and the animal will vacate the nest until it is ready to lay again. If a dwarf does not collect the eggs, the animal will remain on the nest box until the eggs hatch, after which it will also vacate the nest box until it is ready to lay again. In either situation, the nest box remains claimed by the animal. To free the nest for rapid turn around of eggs from a single box, deconstruct the nest after the eggs are collected or hatched and rebuild it - a different animal, ready to lay, will claim the nest box and immediately lay a clutch of eggs.

A nested female will lay eggs regardless of the presence of a male of the same species, however the eggs will not be fertilized and will not hatch unless a male is present. If a male is present, the eggs may be fertilized and hatch if the dwarves can be prevented from collecting them out of the nest box and hauling them to be eaten. To achieve this, eggs can be [[forbidden]], or access to the nest box can be blocked with locked doors, or eggs can be forbidden as a cooking ingredient in the kitchen menu. There may be no way of telling whether or not eggs have been fertilized, but if they sit in a nest box for more than two seasons, they are unlikely to ever hatch. Eggs do not appear to go rotten and can be collected and cooked after two or more seasons without generating [[miasma]].

== Bugs ==

It should be noted that most domestic birds have tremendous reproductive potential, and a few species of breeding birds can cause a population explosion that rivals even the deadliest of [[catsplosion]]s. Entire fortresses can be fed with [[egg production]], although eggs are currently bugged and can cause instant maximum [[clutter]] in your kitchen.{{Bug|3994}}
