Induced Molting of Layer Chickens
(Current as of June 2005)
 

Molting is a natural seasonal event in which birds substantially reduce their feed intake, cease egg production, and replace their plumage. Induced molting is a process that simulates natural molting events. Induced molting extends the productive life of commercial chicken flocks, improves long-term flock health and performance, and results in substantial reduction in the number of chickens needed to produce the nation's egg supply. When birds return to full feed, a new plumage develops and the birds resume egg production at a higher rate with better egg quality. Induced molting also has a positive impact on the environment through reduction of waste and natural resources needed for growing more birds for egg production.

The commercial induced molting procedure is carefully monitored and controlled. Acceptable practices include reduction of photoperiod (day length) and dietary restrictions (including diets of low nutrient density) that result in cessation of egg production. Neither water nor food should be withdrawn. Special attention should be paid to flock health, mortality, and bird weight. Egg quality and safety should be monitored through an egg quality assurance program. The welfare of birds should be a major consideration in this and any management practice.

The AVMA encourages ongoing research into the effect of various methods of induced molting on the performance and well-being of laying chickens.
