They will lay best at 1 to 2 years of age. All pullets (female chicken under 1 year of age) lay small eggs at first and after a while will lay larger eggs. Younger hens will lay 1 egg every 3-4 days. A hen 30 weeks old can lay 2 eggs every 3 days.
Farm chickens can live 4 to 7 years and lay eggs for most of that time. Every year they go âoff-layâ (stop laying eggs) for several months. This happens over the winter, when thereâs too little daylight to trigger egg-laying.Theyâll begin again in the spring.irst, understand that pullets are female chicks who do not yet lay eggs. Most breeds of hens will start laying at 20 weeks (4-6 months of age). The number of eggs depends on the hen. On average, 3 hens should give you 2 eggs a day. So, 18 hens = 84 eggs.
