It is important to point out that force molting is no longer allowed in many countries around the world due to animal welfare concerns.
-
Molting are applied, including feed and water fasting, lighting restriction, and the use of chemical agents.
-
moulting is a process of shedding and renewing feathers.

No extra comment can give. All are given good

Procedure for Forced Moulting
1. Feed Restriction (Most Common Method)
Feed is withdrawn or significantly reduced for a specific period (typically 5–14 days).
Some programs use low-nutrient diets instead of total feed withdrawal to reduce stress.
Calcium levels may be maintained to prevent excessive bone loss.
2. Water Restriction (Rarely Used Due to Welfare Issues)
In some extreme cases, water may be limited for a short time, but this is not recommended.
3. Lighting Control
Light duration is reduced to simulate shorter daylight hours, mimicking natural moulting conditions.
Typically, lighting is reduced to 8 hours per day or even complete darkness.
4. Nutrient Manipulation
Certain moulting programs involve feeding hens a low-energy, high-fiber diet (e.g., wheat bran, alfalfa meal).
Others may use a high-zinc diet to suppress egg production and induce moulting.
5. Post-Moult Recovery
After about 4–6 weeks, normal feeding resumes with a nutritionally balanced layer diet.
-
For a complete recovery of the reproductive tract, the hen’s body weight must drop by 30 to 35 percent during the forced molt. This is typically achieved by withdrawing the hen’s feed for 7–14 days, sometimes up to 28 days.

Forced molting consists of a set of management practices applied to promote stress, inducing birds to stop producing eggs. Several methods to force molting are applied, including feed and water fasting, lighting restriction, and the use of chemical agents.
-
Force moulting : It is achieved by subjecting a flock to a programmed combination of mild environmental stress factors causing the birds to cease laying and consequently moult e.g. decreasing the artificial lighting programme. Force moulting is a practice not normally applicable to the household situation.
-
Reduce their feeds and water for some time. Also reduce the lighting period.

Natural moulting represents the renewal of old feathers few times at different stages of life cycle including the end of the egg laying period. Moulting at different stages : First Moult: It starts when the chick is about 6–8 days old and continues up to 4 weeks, when the early feathers (down) are replaced. Feathers are first lost from the head, neck, then the breast, and finally the tail and wings. Moults can be partial (occurring on particular parts of the body) or complete. Moulting in Pullets: By the time hen start laying eggs they undergo four moults – one complete moult during chick stage and three partial moults (7–9 weeks, 12–16 weeks and 20–22 weeks). The hard tail feathers grow during the moult at 20-22 weeks.
Moulting in Cockerels: During moulting of male chicken, their body weight is reduced, reproductive system is in a resting stage and they are nearly infertile. Moulting in Adult Hens: Normally adult birds moult once in a year (around 16-18 weeks age), but occasionally twice a year or once in two years. During these moults, birds stop egg production and build up their nutrient reserves. This is the most important moult for egg layers to continue their progeny naturally.

laying cycle, where the reproductive system also undergoes complete remodelling
concomitant to feather replacement. Natural moulting represents the renewal of
