Chicks

Chicks are hatchling juvenile birds of domestic chickens (Gallus gallus domesticus). They hatch from eggs after an incubation period of about 21 days and are typically covered with down. They require warmth and a safe, clean environment and access to food and water soon after hatch.

During the first weeks, chicks are kept in a brooder with a controlled temperature, usually starting around 95°F (35°C) and decreasing about 5°F per week as they grow. They need dry bedding, protection from drafts, and ample space. Chicks socialize and establish pecking order as they grow; the flock’s lighting schedule, including day length, influences activity and development.

Nutrition for chicks centers on high-protein starter feeds (approximately 18–22% protein) provided ad libitum, along with clean water. After 6–8 weeks they are typically switched to grower or layer feeds depending on whether they are raised for meat or eggs. Some flocks include grit to aid digestion.

Common health considerations include protection from cold, injury, and predators, plus biosecurity to prevent diseases such as coccidiosis. Hatcheries may vaccinate against Marek’s disease. By about 5–6 months, females (pullets) may begin laying eggs; males (cockerels) reach maturity later. Chicks are kept as backyard poultry, farm stock, or for poultry production.
