Gross anatomical studies were conducted on the thyroid gland of eight weeks old 24 apparently healthy Chabro chickens procured from Poultry Farm, Mathura (India). The chickens were divided into two groups (12 chickens in each group) and reared in summer and winter season. The thyroid gland of chabro chicken was light pink, oval bodies i.e. right and left thyroid located on the ventral surface of the base of the neck just caudal to the junction of subclavian and common carotid arteries. There was 1.8 and three times increase in carcass weight of chicken and weight of thyroid gland, respectively from summer to winter season. The left thyroid gland was situated more cranially than the right thyroid. The average weight of thyroid and all biometrical parameters viz. length, width and thickness were more in winter season reared chickens.
