Hereunder you find the breeding standard of the Aseel as used by the Calcutta Aseel Club. These criteria are still rigourously followed by us in Calcutta.
short, thick, powerful, the colour of ivory and shutting tight. The upper mandible should be straight.
short thick ivory coloured beak
bright, rather prominent, iris white and pearl like, the eyelids a pointed oval, a yellow or bloodshot tinge in the irises is seen in some birds.
Pearlwhite eye colour
COMB - pea or triple comb, short, thick and low (except "Bihangam" strain = single comb Aseel variety).
WATTLES - totally absent (except "Bihangam" strain).Face and earlobes red.
NECK - medium length, inclined to short, the neck bone next to the skull prominent, thus giving it the shape of a cobra's open hood. The neck bones small, the ridges fleshless, thick to feel, especially 2 or 3 inches (5 to 7½ Cm) below the head. On the whole strong like an iron rod, covered with wiry feathers.
BACK - broad and flat. Viewed from above back and wings are heart shaped.
WINGS - carried well apart from the body and held high in a fit bird. They must be muscular and fleshless, with hard strong rather strong quill feathers.
CHEST - Thrown out, wide, muscular, hard, the flesh where showing through the feathers on breast, thighs and shoulder joints.
STERN - The belly small, "the Pope's Nose" large, broad and very strong (IMPORTANT POINT !), the sickle feathers narrow, scimitar shaped, wiry, pointed, drooping from the base, less curved than other breeds, feathers irridescent, not carried above the horizontal, close together, but not shut up, cloak and and saddle feathers pointing backward than in other breeds, tough, pointed and beautiful.
BODY - compact and muscular
THIGHS - Not to long, large, round, hard muscular, and sparsely feathered (the flesh often shining through), in line with the body, and not so wide as his wings when the bird faces you, as such a bird would be unable to strike properly.
LEGS - Thick and square, down the front, not round in matured birds. The meeting of the scales makes a straight line slightly indented. White is the only colour acceptable, but the legs often turn yellow due to feeding of green plants.
TOES - Straight, thick, yet tapering and strong, nails very broad, strong, curved and white.
APPERANCE - the carriage of the Aseel has to be upright, standing firmly and well on its legs, the bird handsome, sprightly and shapely, and quick as a cobra in its movements. A standing bird viewed from the side should have its eye and middle toe nail in a parallel line.
CHARACTERISTICS - the crow of the Aseel is unlike that of any other breed, being short, as if cut off at the end. The plumage has little or no underfluff. The weight of an adult cock in proper condition should not exceed 3 Kilograms (7 Lbs). The hen with exemptions for sex typical physical points , should resemble the cock in all points. The Aseel when tickeled or touched lightly near the vent at once begins to preen and oil its feathers. This characteristic behaviour applies in lesser degree to birds who are only a remote cross with Aseel blood. The purebred Aseel hens go with their chicks from 6 months to 1 year. This unlike the ordinary hens doing this for 6 weeks. Aseel hens lay around 2 clutches of eggs in a year.
