Why would poultry farmer buy only one day old chickens and not older birds?

Poultry farmers often buy one-day-old chicks to ensure better control over their growth and development. By starting with younger birds, they can manage their diet, environment, and health from the very beginning, leading to healthier flocks and improved productivity. Additionally, younger chicks tend to adapt more easily to their new surroundings, reducing stress and mortality rates compared to older birds. Finally, purchasing day-old chicks can be more cost-effective, as they are generally less expensive than fully grown birds.
