A small, domesticated waterfowl, '''Ducks''', called '''ducklings''' as babies, are not found in the wild, and can only be [[Trade#By_inventory|purchased from traders]] or received in [[Events#Animal_self-tamed|self-taming events]]. Like [[chicken]]s, ducks mature quickly and lay eggs often, making them both good meal birds and sources of [[Duck egg (unfert.)|eggs]]. Males of the species can be distinguished by their green heads and two-tone body while females have a solid colour head and body with darker wings.

== Summary == 
{{Pen Animal Note|Ducks}}

A female duck produces {{P|Eggs Per Clutch Average}} [[egg]] every {{P|Egg Laying Interval}} day. Ducks can lay both [[Chicken egg (unfert.)|unfertilized]] and [[Chicken egg (fert.)|fertilized]] eggs, depending on if it has mated with a male.

== Analysis ==
Ducks are the second best animal for egg production, and one of the best overall animals for meat production. Ducks reproduce rapidly.

Ducks are nearly identical to [[chicken]]s, providing the same yields in both meat and eggs. However, ducks consume 20% more nutrition, meaning that chickens are better livestock. If chickens are not available but ducks are, then ducks can be a suitable replacement. 

===Eggs===
An adult duck consumes {{P|Real Hunger Rate}} nutrition per day, and produces {{#vardefineecho:egg_nutr_per_day|{{#expr:{{P|Eggs Per Clutch Average}}/{{P|Egg Laying Interval}}*{{Q|Chicken egg (unfert.)|Nutrition}}}}}} nutrition of eggs each day. This results in a nutrition efficiency of {{%|{{#var:egg_nutr_per_day}}/({{P|Base Hunger Rate}}*1.6) round 3}} when unfertilized eggs are eaten. [[Overeating]], and the existence of males, will lower nutrition efficiency in practice.

Note that slaughtering ducklings gives more nutrition than eating unhatched eggs (0.6 from meat rather than {{Q|Duck egg (fert.)|Nutrition}} from 1 egg). However, a handler has to actually slaughter each duck, and a butcher's yields are multiplied by [[Butchery Efficiency]]. So if you don't a skilled cook, eggs may be better for nutrition. Also, eggs are vegetarian.

===Meat===
When slaughtered, a duck yields {{#vardefineecho:baby_meat|{{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.1*140}}}}}} meat as a duckling; {{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.5*140}}}} as a juvenile; or {{Meat Leather Curve|{{#expr:{{P|Body Size}}*140}}}} as an adult. No leather is yielded.

When ducklings are slaughtered, an always-fertilized female duck produces {{#expr:{{Meat Production|{{PAGENAME}}|Baby}} round 2}} nutrition per day, resulting in a nutrition efficiency of {{%|{{Meat Production|{{PAGENAME}}|Baby}}/({{P|Base Hunger Rate}}*1.6) round 3}} when not considering males, or {{%|{{Meat Production|{{PAGENAME}}|Baby|{{#vardefineecho:femaleratio|{{#expr: 2/3*24*{{P|Egg Laying Interval}}/{{P|Mate Mtb Hours}} round 2}}}}}}/{{Nutrition Consumption|{{PAGENAME}}|Baby|{{#var:femaleratio}}|1}} round 3}} when accounting for the {{#var:femaleratio}}:1 hen:rooster ratio needed to achieve a good [[Animals#Mating|fertilization rate]].

As a duck grows into adulthood, it will consume {{#expr:{{Consumption Upto Adulthood}} round 2}} nutrition in total, and will yield {{#expr:0.05*({{P|Meat Yield}} - {{#var:baby_meat}})}} more nutrition when slaughtered than it would as a baby. Therefore, it is better to slaughter ducks as soon as they hatch from an egg.

When slaughtered as ducklings, ducks are better than almost all animals in terms of theoretical meat : food consumption ratio, below [[chicken]]s and [[tortoise]]s. This efficiency is lower than it seems, as ducks are prone to [[overeating]]. Due to the amount of slaughtering required with ducks, players may prefer to ranch [[horse]]s or [[ibex]] instead.

=== Feeding ===
A duck consumes {{#Expr: 1.6 * {{P|Base Hunger Rate}}}} nutrition per day, or roughly {{#Expr: ceil(1.6 * {{P|Base Hunger Rate}}/{{Q|Hay|Nutrition}})}} [[hay]].

The following is a list of how many tiles of [[haygrass]] it takes to sustain a mature duck. 
* '''Gravel:''' {{#Expr: ceil(1.6 * {{P|Base Hunger Rate}}/{{Q|Hay|Nutrition}})/({{Q|Haygrass|Harvest Yield}}/({{Q|Haygrass|Real Grow Days}} / (((0.7-1)*{{Q|Haygrass|Fertility Sensitivity}}) + 1))) round 2}}
* '''Soil:''' {{#Expr: ceil(1.6 * {{P|Base Hunger Rate}}/{{Q|Hay|Nutrition}})/({{Q|Haygrass|Harvest Yield}}/({{Q|Haygrass|Real Grow Days}} / (((1.0-1)*{{Q|Haygrass|Fertility Sensitivity}}) + 1))) round 2}}
* '''Rich Soil:''' {{#Expr: ceil(1.6 * {{P|Base Hunger Rate}}/{{Q|Hay|Nutrition}})/({{Q|Haygrass|Harvest Yield}}/({{Q|Haygrass|Real Grow Days}} / (((1.4-1)*{{Q|Haygrass|Fertility Sensitivity}}) + 1))) round 2}}
