Hen

Hen is a harmless non-hostile creature that spawns above ground in Forest World.

Characteristics
Hens have no breeding system and will spawn randomly on the surface periodically to maintain a constant world population.

Hens will attempt to flee when attacked. They are quite fast and can be difficult for dwarfs to catch and kill; herd them into corners or holes for easier hunting. They are able to enter shelters through open doors and hatches and frequently fall down holes and mineshafts and are usually unable to find their way out.

When killed, hens will drop eggs and feathers and are the only source for these two ingredients.

Hens can also be trapped and fenced in a farm to produce egg and feather regularly.
