Answer: Option A

Egg production starts in poultry at the age of $$5\frac{1}{2}$$ months.
Birds usually start to lay at around five months (20 - 21 weeks) of age and continue to lay for 12 months (52 weeks) on average, laying fewer eggs as they near the moulting period.
During ideal day length (14 - 16 hours of light) and with adequate nutrition, housing, and management, hens (depending on breed) should begin producing eggs when they are 18 - 22 weeks old.
