The heating and ventilation systems in a poultry house must be continuously monitored to keep the moisture content of the litter controlled so that the litter remains friable (easily broken up or crumbly). If the litter becomes too wet and the litter is allowed to become "sealed", then the birds will be living on a damp, slippery and sticky ...
Worldwide, in 2005 production was 71,851,000 tonnes. From 1985 to 2005, the broiler industry grew by 158%. [1] A key measure of performance is the feed conversion ratio (FCR), the ability to convert feed into edible product. In 2018 the FCR of broilers is about 1.5, or 1.5 kg of feed to produce 1 kg of meat. [2]
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]

In the first week of a broiler's life, it can grow up to 300 percent of its body size. A nine-week-old broiler averages over 9 pounds (4 kg) in body weight. At nine weeks, a hen will average around 7 pounds (3.2 kg) and a rooster will weigh around 12 pounds (5.5 kg), having a nine-pound (4 kg) average. Broilers are not raised in cages.
Modern varieties however grow much faster; by day 35 a Ross 708 broiler may weigh 1.8 kg (4.0 lb) as against the 1.05 kg (2.3 lb) of a heritage chicken of the same age. [ 22 ] Adult chickens of both sexes have a fleshy crest on their heads called a comb or cockscomb, and hanging flaps of skin on either side under their beaks called wattles ...
