Introduction. The age at which your hens will begin to lay depends on their breed type. Hybrids are the earliest birds to start laying, starting about 1 month earlier than non-hybrids. Non-hybrids, which include our rare and heritage breeds, typically begin laying about one month later than hybrids. Most of the egg laying hybrids start laying at 4 to 5 months of age. These include Pearl White Leghorns, Black Stars, and Red Stars. Hybrid egg layers are bred by crossing two different lines or breeds. They are known for their excellent productivity and high feed conversion ratio.
The laying cycle of a chicken flock usually covers a span of about 12 months. Egg production begins when the birds reach about 18-22 weeks of age, depending on the breed and season.Flock production rises sharply and reaches a peak of about 90%, 6-8 weeks later.Production then gradually declines to about 65% after 12 months of lay.A typical production curve for a laying flock, showing changes in the level of egg production and in egg weight, over time, is given in Figure 1.nfection with the fowl pox virus will cause the chickens to have poor growth, poor feed conversion and a precipitous fall in egg production. Fowl pox may affect any age bird. It is transmittedby direct contact with an infected chicken or by mosquitos.
