Most ducks will stay on the nest and incubate their eggs for 27 days. They will not start incubating until the last egg has been laid, usually laying one egg per day.
18-21 days
In canaries, after mating, the female typically lays eggs about 5 to 7 days later. The eggs are usually laid one at a time, with a clutch consisting of 3 to 6 eggs. The entire process from mating to the first egg being laid can take around a week. After laying, the female will incubate the eggs until they hatch, which usually occurs about 13 to 14 days later.
Maybe a couple of days. When it is ready the shell cracks a little bit everyday :)
After mating, it takes approximately 2 months for the eggs to be laid, and then another 2 months for the eggs to hatch.
21 to 30 days
After mating and building the nest, there is approximately 2-3 weeks before the egg laying begins. Once the female begins to lay, she will produce a new egg every 12-24 hours and it can take up to 2-3 weeks before all the eggs are laid. Once she has laid all her eggs then the incubation period begins and usually lasts about 6 weeks before hatching. Males and Females alternate sitting on the eggs during the incubation period.
It depends what animal it is.
They are toads' eggs, which are laid in long strings parallel to each other. They are often stuck to aquatic vegetation.
The egg. Dinosaurs laid eggs long, long before chickens existed.
House flies typically lay eggs about 24 to 48 hours after mating. The female can produce several batches of eggs, depositing around 100 to 150 eggs at a time. These eggs are usually laid in decaying organic matter, which provides nourishment for the larvae once they hatch. The entire life cycle from egg to adult can be completed in as little as 7 to 10 days under optimal conditions.
