It is known as a coop or a pen.
On farms and in backyards all over the world. The specific place a flock is housed is called a chicken coop. Some chickens are kept in cages and many are what is called cage free by the poultry industry, this means they are not kept in cages but allowed to roam within the confines of a large building. Free range chickens are those allowed to wander at will around farmyards and backyards, eating fresh vegetation and insects.
Cattle farms, gator farms, pig farms, chicken farms, horse farms, etc.
I have never seen chicken eggs so wild and crazy that they needed to be caged. But seriously, nearly all egg farms are now finding ways to get their layer hens out of cages and into large barn settings to produce their eggs.
Mostly cages, fences, machinery, animals, concrete sheds and grass.

Organic farms, commercial farms, "factory" farms, grain farms, ranches, chicken farms, pig farms, dairy farms, beef farms, bison ranches, etc.

The cages I think you are referring to are usually called a trellis. As far as the sticks.....They are called stakes. There are numerous varieties.....The ones they use for tomatoes are called "cages" is that what you were thinking of?
