Answer 1

Female ostrich discards extra eggs from weaker females and dominant female lays of her first egg expect leaving about in most of the 20% cases. Fertilized eggs in a single communal nest present in the female ostrich lays and are 3m wide or 30-60 cm deep in the structure.

Complete answer:
The egg present in the ostrich incubated by the male’s night and by the females by day, to escape detection of the nest with the use of coloration of the two sexes. In the communal nest distinguish her own eggs from the common ostrich. The smallest eggs that’s relative to the size of the adult bird are 13 cm wide and 1.4 kg kilograms, more than the 20 times weight of the chicken’s egg and 1-4% as compared to the size of the female. Small pits marked by the thick shells and are glossy cream colored eggs present in the ostrich females.
This is the high rate of predictions and the incubation period of the ostrich female and male eggs 35to 45 days as compared to the ratites. Males and females cooperate in rearing chicks but only male defend hatchlings and teach them to feed. Only 15% survive to 1 year of age but fewer than 10% nests survive only 9 week of the period.

Therefore the correct option is (D).
