{{Pen Animal Note|Chickens}}
  
Chickens are some of the fastest reproducing animals in the game so <s>some</s> extreme care must be taken to keep chicken populations under control or you'll quickly find your colony overwhelmed. It is easy for a dozen hens to quickly produce hundreds of chicks, and although individual chicks are easy to maintain, a sudden surge can quickly overwhelm your food supply. Chicken feed is accomplished by growing [[haygrass]], though handling large farms will be taxing on hauling labor without the help of trained dogs - or [[Grizzly bear|bears]] (or [[Thrumbo|Thrumbos]] if that's your style, although half of your haygrass field would be ruthlessly devoured before actually being hauled) as Haygrass stacks up to 200.
+
A female chicken produces {{P|Eggs Per Clutch Average}} [[egg]] every {{P|Egg Laying Interval}} day. Chickens can lay both [[Chicken egg (unfert.)|unfertilized]] and [[Chicken egg (fert.)|fertilized]] eggs, depending on if it has mated with a rooster.
  
A clutch of freshly hatched chickens can be slaughtered for a modest amount of meat or sold to merchants as a <span class="plainlinks">[http://ludeon.com/blog/studio/ Ludeon]</span>icrous source of income.
+
== Analysis ==
 +
Chickens are the best animal for egg production, and one of the best animals for meat production.
  
Keep your chickens far from Foxes and Cobras because they usually hunt them. Or don't. It doesn't really matter because the losses are quickly replenished.
+
Chickens grow very quickly, taking only {{#expr:{{P|Maturity Age}}*60 round 1}} days to mature, placing them among the fastest-growing animals. Combined with their incredibly fast reproduction rate of {{#expr:{{P|Eggs Per Clutch Average}}/{{P|Egg Laying Interval}}}} offspring per day, a population of chickens can rapidly explode from a single rooster and hen, theoretically increasing to a population of 1200 adults within the span of just a year. Once the population explosion gets going, the population will double every approximately 5.7 days.<!--simulated with clutch_size=1, egg_interval=1, maturity_age=12-->
  
<!--Don't get angry guys, I didn't vandalize anything-->
+
Chickens are nearly identical to [[duck]]s. Ducks provide the same yield in both meat and eggs. But ducks consume 20% more nutrition, so they are inferior as livestock.
===Training===
+
 
Chickens lack the intelligence for training. You can, however, make battle chickens by using [[Zone/Area#Animal area|animal areas]] to create choke points for your enemies.
+
=== Eggs ===
 +
An adult hen 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 roosters, will lower nutrition efficiency in practice.
 +
 
 +
Note that slaughtering chicks gives more nutrition than eating unhatched eggs (0.6 from meat rather than {{Q|Chicken egg (fert.)|Nutrition}} from 1 egg). Note that a rooster has to fertilize each hen, that hens have to be slaughtered, and that a butcher's yields are multiplied by [[Butchery Efficiency]]. So if you don't have a skilled cook, eggs may be better for nutrition. Also, eggs are vegetarian.
 +
 
 +
=== Meat ===
 +
When slaughtered, a chicken yields {{#vardefineecho:baby_meat|{{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.1*140}}}}}} meat as a chick; {{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 chicks are slaughtered, an always-fertilized hen 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}} for the hen alone, 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 chick 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. Due to the effects of [[overeating]], letting chickens grow up is a slight malus to meat yield. Despite being slightly worse, you may prefer to let chicks grow up, as slaughtering adult chickens takes less work.
 +
 
 +
Chickens are the best pen animal for nutritional efficiency. The main competitors are the [[ibex]] and [[tortoise]]. [[Ibex]] are less efficient, but take far less slaughtering work. [[Tortoise]]s aren't pen animals, meaning they must be re-tamed over time, but are even better for nutrition.
 +
 
 +

 +
Chicken's rapid reproduction makes them good fodder for the  [[Persona traits#Kill-focused|Kill-focused]] persona trait.{{RoyaltyIcon}} This persona trait grants +20% [[psyfocus]]{{RoyaltyIcon}} whenever its wielder kills any pawn, even when slaughtering chickens or chicks.

Chickens can not be found in the wild; they must be bought from a merchant or join the colony in a self-taming event. Males of the species are referred to as Roosters and can be distinguished by their ruddy brown coloration, while females are referred to as Hens and are white. Babies of either gender are bright yellow and referred to as Chicks.

Summary

Chickens are pen animals. Once tamed, pen animals cannot and do not need to be trained any further. But if left outside of a pen or caravan hitching spot, pen animals will eventually roam outside your colony. Making a caravan is not required to tie animals to a caravan hitching spot.

A female chicken produces 1 egg every 1 day. Chickens can lay both unfertilized and fertilized eggs, depending on if it has mated with a rooster.

Analysis

Chickens are the best animal for egg production, and one of the best animals for meat production.

Chickens grow very quickly, taking only 12 days to mature, placing them among the fastest-growing animals. Combined with their incredibly fast reproduction rate of 1 offspring per day, a population of chickens can rapidly explode from a single rooster and hen, theoretically increasing to a population of 1200 adults within the span of just a year. Once the population explosion gets going, the population will double every approximately 5.7 days.

Chickens are nearly identical to ducks. Ducks provide the same yield in both meat and eggs. But ducks consume 20% more nutrition, so they are inferior as livestock.

Eggs

An adult hen consumes 0.22 nutrition per day, and produces 0.25 nutrition of eggs each day. This results in a nutrition efficiency of 111.6% when unfertilized eggs are eaten. Overeating, and the existence of roosters, will lower nutrition efficiency in practice.

Note that slaughtering chicks gives more nutrition than eating unhatched eggs (0.6 from meat rather than 0.25 from 1 egg). Note that a rooster has to fertilize each hen, that hens have to be slaughtered, and that a butcher's yields are multiplied by Butchery Efficiency. So if you don't have a skilled cook, eggs may be better for nutrition. Also, eggs are vegetarian.

Meat

When slaughtered, a chicken yields 12 meat as a chick; 26 as a juvenile; or 42 as an adult. No leather is yielded.

When chicks are slaughtered, an always-fertilized hen produces 0.6 nutrition per day, resulting in a nutrition efficiency of 267.9% for the hen alone, or 178.6% when accounting for the 2:1 hen:rooster ratio needed to achieve a good fertilization rate.

As a chick grows into adulthood, it will consume 1.45 nutrition in total, and will yield 1.5 more nutrition when slaughtered than it would as a baby. Due to the effects of overeating, letting chickens grow up is a slight malus to meat yield. Despite being slightly worse, you may prefer to let chicks grow up, as slaughtering adult chickens takes less work.

Chickens are the best pen animal for nutritional efficiency. The main competitors are the ibex and tortoise. Ibex are less efficient, but take far less slaughtering work. Tortoises aren't pen animals, meaning they must be re-tamed over time, but are even better for nutrition.

Kill-focused

Chicken's rapid reproduction makes them good fodder for the Kill-focused persona trait.Content added by the Royalty DLC This persona trait grants +20% psyfocusContent added by the Royalty DLC whenever its wielder kills any pawn, even when slaughtering chickens or chicks. A coop can allow rapid use of psycasts, such as word of inspiration, which would otherwise be limited by psyfocus.

Training

Chickens lack the intelligence for training.

This animal can be trained as follows:

Attack:  Ex.png
Rescue:  Ex.png
Haul:  Ex.png

*As of version 1.1.2610, all animals can be tamed. The percentage of likelihood of success depends on factors such as the Animals Wildness Percentage, Pawn Handling Skill, and others. More information can be found on the animals page.

  1. Coverage determines the chance to hit this body part. It refers to the percentage of the super-part that this part covers, before its own sub-parts claim their own percentage. For example, if the base coverage of the super-part is 100%, and the coverage of the part is 20%, 20% of hits would hit the part, and 80% the super-part. If the part had its own sub-part with 50% coverage, the chances would be 10% sub-part, 10% part, 80% super part.
  2. Target Chance is the actual chance for each part to be be selected as the target when each part's coverage has been taken into account(I.E. Neck covers 7.5% of Torso but Head covers 80% of Neck so it actually has only a 1.5% chance to be selected). This is not pure hit chance, as different damage types propagate damage in different ways. See that page for details.
  3. Note that capacities can affect other capacities in turn. Only the primary effect is listed. See specific pages for details.
  4. This is the part that everything else connects to to be considered 'connected'.
  5. If Moving drops below 16% a pawn cannot move.
  6. Note that eating won't go below 10%.
