Poultry refers to domesticated birds bred for consumption and includes chicken, duck, goose, guinea, pigeon, and turkey. Poultry meat can be white or dark, with dark meat containing more fat and myoglobin. Chicken is the most commonly eaten poultry and comes in classes like broiler, roaster, and hen based on age. Proper handling and storage of poultry is important to prevent bacterial contamination as it is highly perishable.
