When does egg production begin in chickens?

• A. 12 weeks
• B. 19 weeks
• C. 24 weeks
• D. 30 weeks

Answer: (B)

Egg production starts when pullets reach reproductive maturity and the hormonal changes triggered by longer daylight promote ovulation. In chickens, this onset typically occurs around 5 months of age, often within a window of roughly 18 to 22 weeks. Breed differences matter: some fast-maturing breeds lay earlier, while slower-maturing ones may start a bit later. Environmental factors such as adequate nutrition and increasing day length can push the start of laying earlier, whereas poor conditions can delay it.

Given that context, starting to lay around 19 weeks fits the common timeline for many hens, making it the best answer. A start around 12 weeks is too early—the birds are usually still growing and not reproductively ready. Waiting until 24 weeks or 30 weeks is later than typical onset for most layer birds.
