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.
18-21 days
It depends what animal it is.
30 days
yes they lay it right after mating
How long do house flies live
Female dogs do not have mature eggs waiting for fertilization like some other animals. Instead, the eggs are released during the female's heat cycle, which can happen in response to mating. Once released, the eggs can be fertilized by sperm from the male dog.
Female red-eared sliders typically lay eggs about 2 to 4 weeks after mating.
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.
After mating, it takes approximately 2 months for the eggs to be laid, and then another 2 months for the eggs to hatch.
Maybe a couple of days. When it is ready the shell cracks a little bit everyday :)

House flies have a powerful sense of smell, enabling them to detect sources of food--such as your garbage--from long distances. Once a fly gets into your house, it lays eggs on the garbage or other source of food. When the eggs hatch soon thereafter, you have instant flies all over the place.
