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.
Creation[edit]
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, query the workshop, select wood products, then use +/- to manually highlight "Make wooden Nest Box", or select g rock products, then use +/- to manually highlight "Make rock Nest Box".
- For a glass nest box, query the workshop, select green/clear/k crystal glass, then use +/- to manually highlight "Make type glass Nest Box".
- For either forge, query the forge, select other objects, then use +/- to manually highlight the metal and then use +/- to manually highlight "Make metal Nest Box".
Construction and use[edit]
Once created, the nest box is then built using 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 eggs 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.
Fertilized eggs[edit]
A nested female will lay eggs regardless of the presence of a male of the same species, however the eggs will not be fertilized unless a male is present. Hatching does not require male to be around, once the eggs are fertilized and laid. 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 and disabled in all food stockpiles reachable from the nest. 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.
Incubation Chamber[edit]
A simple way to make sure that eggs can hatch without having dwarves try to make omelettes out of them is to build incubation chambers for your female birds.
- Build 1x1 rooms, with lockable doors.
- Put one nest box in each room.
- Create a 1x1 pasture zone on top of the nest box, and assign one female egg-layer to it. She should claim the nest box when she is ready to lay eggs.
- Pasture or chain at least one male of the species somewhere. It needn't be close to the nest box.
- When you want the eggs to remain undisturbed, lock the door to the room.
If the eggs are fertile, you should eventually get a message about eggs having hatched. When you do, go to the nest box and unlock the door so the crowded chicks can get out (crowded animals will fight, and if they do, you may lose a chick or two in the melee; luckily they are always much smaller than their mother and unlikely to hurt her.)
It's a good idea to keep a cage nearby to assign newly hatched chicks to, so they won't get in the way and lower your FPS. When they are grown, they can be re-assigned to pastures for breeding or egg-laying, or butchered.
Forging and Melting[edit]
- Metal nest boxes cost one metal bar to forge, or one adamantine wafer.
- When a nest box is melted down, it will return 0.3 metal bars/adamantine wafers for an efficiency of 30%
Bugs[edit]
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 catsplosions. Entire fortresses can be fed with egg production. It is unclear whether this behaviour is a bug or a feature, as the indicated clutch sizes in the raws are meant to match those of real life - and are sometimes lower in the case of reptiles. The root of the problem may be high survival rate of hatchlings in DF unless something kills them all.
Elk birds are both grazers and egg layers. Females left undisturbed near a nest box will probably starve themselves to death (certainly, if there are no males available).Bug:4637
Aquatic creatures (such as sea serpents) refuse to use a submerged nest box, making them unable to breed.Bug:4105
