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.
It takes a mallard duck 28-30 days for the eggs to hatch. All of the eggs will hatch within 24 hours and they will then head for water. Never to return to the nest.

After mating, it takes approximately 2 months for the eggs to be laid, and then another 2 months for the eggs to hatch.
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.
