I would second the advice to go to www.backyardchickens.com/forums . There is a duck category there, and you will get quick, knowledgeable answers to your questions.
Ducks DO lay in water, but it's more an accidental thing. If they want to brood, they will lay in a nest. Most are not particularly broody and will lay wherever they happen to be. In fact, if you want the eggs, it's usually best to keep them in the coop in the early morning until they lay, so you will be able to collect them.
Birds don't get "pregnant". If the eggs are going to be fertilized, they are fertilized inside the female's body. Once the eggs are laid, they are either fertile and can hatch, or are not. Duck eggs will NOT hatch unless they are incubated. They don't begin to develop unless they are kept very warm and at proper humidity, usually under the mother duck or in an incubator.
A typical lay cycle for most ducks varies by breed, but will be anywhere from one per day (for Indian Runners and other laying breeds) to one every few days. Some ducks lay year-round (my runners did) and some lay seasonally. If they are going to brood (sit on the eggs) they will typically lay one egg at a time in the nest until they think they have enough, and then will begin setting on them and stop laying. Some types of ducks go through this cycle about 3x a year (muscovies, especially in places where it is not very hot year-round).
