(1) Advantages: Forced moulting prolongs the useful life of laying hens and reduces the cost of breeding broilers. During the second laying period, the hens have a high survival rate and a large egg size. The moulting period is shortened and the natural change is allowed. Feather takes 2 months, and artificial forced moulting takes only 5 months; according to market demand, control of the period of production and egg production. (2) Disadvantages: The second laying period after forced moulting is 6 months shorter than the first laying period; body weight is large, maintenance needs more, and feed efficiency is low. Whether or not to use forced moulting to raise two-year-old chickens should be determined according to market needs and the condition of the flock. If the chickens are healthy and disease-free, the chicken species are excellent and not easy to buy. The first egg production stage has high egg production levels, either because there are no brooding facilities, there are no new chickens to renew the flock, or in order to use the two-year-old chickens, the disease resistance is strong. The major eggs and other advantages can be used for forced moulting, feeding two years of chicken. China Agricultural Network Editor
