Description

Chickens are hatched by dropping a Fertilized Egg in the right conditions (20C-30C). The chick will hatch out of the egg after a few minutes. The chicken should lay a Fertilized Egg and some Unfertilized Eggs before it dies (numbers may very depending on conditions Needs more research). Chickens do not appear to eat Potatoes or Ferns but will eat Corn, Wheat and Soybeans. A chick or chicken is much like a plant and will display a life bar when in need of something.

Warning: Chickens will eat items contained in closed storage boxes, lockers and stored on your character. They will also consume live vegetation so be very careful about where you let them go.

Info
Pressure	Normal Human should be good 50kPa-100kPa
Temperature	On Europa (100% o2) it survives at the harsh -150°C
Atmosphere	>10% o2 at 50kPa ?
Longest Life Span	? Days (possibly infinite)
Crops Consumed Per Day	40
Fertilized Eggs laid	1 ?
Unfertilized Eggs laid	5 ?

The Chicken lays an egg every 1-1.5 minutes. With probability of 15% the egg will be fertilized.

Chicken Stats

My 1st Chicken managed to eat 26 wheat, 8 corn and 5 soy in about a day and a half. I strongly suggest rationing! It also produced 6 Unfertilized Eggs and 1 Fertilized Egg. I Suspect they produce 1 Fertilized Egg per day. My chicken managed to produce an egg even though it was starving suggesting a time delay and not health dependencies. My 1st Chick also consumed 7mols of O2 in that time.

My 2nd Chicken lasted 2 full days eating 80 corn and produced 6 Fertilized Eggs and 6 Unfertilized Eggs before dying of starvation.

My 1st Chicken Batch: 6 chickens ( Unfed ) lasted about half a day producing 3 eggs each. 4 Fertilized Eggs and 14 Unfertilized Eggs. Need to replay tests to check results

Chickens require much more food than your player will usually need

Another set of observations done at normal difficulty on Mars got the following results:

chickens...
...need an oxygen ratio of 10% or more, lowest allowed pressure is around 1.5kPa at 20°C (but this could also be a "mol per grid" kind of value)
...consume a tiny amount of oxygen (approximately 0.001 mol per second) but doesn't produce any CO2
...will fall unconscious when suffocating which stops them from laying eggs
...eat only when they are hungry (eating 1 corn added 2.5 to the <Nutrition> parameter in world.xml, when taking starvation damage it could eat 2 corns at once)
...take damage from suffocation (very slowly), starvation, storms, explosions and catching on fire (when the atmosphere is burning)
...take no damage from temperature (tested with -200°C and 400°C)
...lay an egg every 400 seconds on average (the <LayEggTimer> parameter in world.xml appears to be in game-ticks)
...are paralyzed when inside a 1x1 area (will not walk or jump), but will still lay eggs and eat (railings makes eggs easy to reach)

fertilized eggs...
...can only hatch when the temperature is 15.15°C or above (at any pressure in any gas) (very useful to prevent overpopulation)
...will hatch after 2 minutes on the floor, after approximately 2.5 more minutes the chick mature into an adult
...will not hatch when stored in lockers
...are laid randomly 10-20% of the time
