2.
The germinal disc of a fertile egg, which is always round and exhibits a characteristic doughnut shape with a white symmetrical ring and a clear center. It is larger than the blastodisc and represents the early stage of embryo development before incubation.
(10 harf)
5.
A temporary, sharp, horn-like projection on the tip of the embryo's beak used to pierce the internal membrane and shell during hatching. It is absent in embryos that die before day 6 but is clearly visible on embryos dying from day 7 to 17.
(8 harf)
6.
An egg in which the mature embryo has successfully broken through the shell using its egg tooth but has died before completing the emergence process. This indicates a failure in the final stages of hatching.
(9 harf)
7.
A systematic diagnostic procedure where unhatched or candled-out eggs are opened and examined to determine fertility status and the exact stage of embryonic mortality. This ••• helps identify whether hatchability problems stem from breeder farm management or hatchery operations.
(16 harf)
8.
The germinal disc of an infertile egg, characterized by irregular or jagged edges and a small, intense, often granulated white spot. It is rarely perfectly round and frequently contains multiple vacuoles or bubbles.
(10 harf)
9.
Structural or anatomical abnormalities in the developing embryo, such as missing limbs, duplicate parts, or head deformities, which often result from genetic factors, extreme incubation temperatures, or nutritional deficiencies.
(12 harf)

1.
An abnormal physical orientation of the embryo within the egg close to the time of hatching, which prevents it from successfully pipping or exiting the shell. Correct positioning is crucial for a successful hatch.
(11 harf)
3.
Small epidermal invaginations on the embryo's skin from which ••• develop, becoming visible around the 8th day of incubation. Their presence helps pinpoint embryonic death to the mid-incubation period.
(16 harf)
4.
The invasion and proliferation of bacteria, molds, or other pathogens within the egg, often leading to embryo death, rot, or exploding eggs during incubation. It is usually caused by poor nest hygiene or improper egg washing.
