Five-day-old broiler strain Cornish-Rock chicks. Hatcheries take the fertilized eggs, incubate them, and produce day-old broiler chicks. [citation needed] Incubation takes about 21 days, and is often a two-step process. Initial incubation is done in machines known as setters. A modern setter is the size of a large room, with a central corridor ...
For a flock of, say, six chickens, that translates to a 6'-by-4' nesting coop plus a 6'-by-10' run. (See below for more scoop on chicken coops.) In reality, the amount of room is rarely the deal ...

[8] For privately raised chickens, or chickens as pets, feed can be delivered through jar, trough or tube feeders. The use of poultry feed can also be supplemented with food found through foraging.

In poultry farming, early feeding is the ad lib availability of feed and water for day-old chicks from the moment of hatching from the egg. Early feeding has a positive effect on chick performance because development and maturation of important organs is not retarded post hatch, but continues.
In the U.S., the average feed conversion ratio (FCR) of a broiler was 1.91 kilograms of feed per kilograms of liveweight in 2011, an improvement from 4.70 in 1925. [18] Canada has a typical FCR of 1.72. [19] New Zealand commercial broiler farms have recorded the world's best broiler chicken FCR at 1.38. [20]
Poultry feed can include roxarsone or nitarsone, arsenical antimicrobial drugs that also promote growth. Roxarsone was used as a broiler starter by about 70% of the broiler growers between 1995 and 2000. [75] The drugs have generated controversy because it contains arsenic, which is highly toxic to humans. This arsenic could be transmitted ...
