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.
It's completely dependent on the breed of the bird. Some commercial hybrids will lay 6-7 eggs a week like clockwork for their first laying year (a laying year being from 6mos old to 18 mos old) and then 5-6 eggs the next year. Some breeds will start at 5 eggs a week their first laying year and then go down from there. The biggest thing to remember is that any chicken will decrease her egg production by about 20% each year. So (using 100 to make the math easy) if she lays 100 eggs the first year, she'll lay 80 the next.
