Laying cycle is the period in which a hen produces eggs, starting from the point of maturity until production declines.
Most hens begin laying at about five to six months of age. The first months usually give the highest egg production, sometimes up to 80–90 percent of the flock laying daily. Production gradually drops as hens grow older, and farmers often cull or replace birds after one or two years. Good management, balanced feed, and proper lighting can extend the laying cycle and improve egg numbers.
