Yes, otherwise The egg wouldn't be fertile, and wouldn't actually contain a duckling, and the egg would just go rotten.
No, drakes (male ducks) do not take care of the eggs once the female lays them. It is the female duck that incubates the eggs and cares for the ducklings after they hatch. Male ducks typically do not play a role in nesting or rearing the young.
In eggs
No you need to have a female and male duck to have baby ducks.
the ducks hatch in the spring normaly in the 2nd week
Yes ducks can lay eggs without mating, the won't be fertile, they need to mate for that and to have baby ducks maybe by artificial insemination? are you asking if they artificially inseminate ducks?
the mother finds a mate and after they take care of their business, a few or so weeks later the mother lays eggs which will, in a couple of weeks and mom's care, will hatch into baby ducklings
The fertilized egg develops after it's laid. The developing embryo grows inside the egg until it's grown enough to hatch out. The egg contains a tiny air-sac to allow the baby duck to take a breath while it fights to break the shell. The babies are alive inside the egg.
the fact about duck eggs are that it take about 28 day to hatch.
Wild ducks certainly do and many farms have ducks that set eggs each spring but there are hatcheries that incubate duck eggs just as most chickens are produced in a hatchery.
Birds have an opening called a cloaca that acts for both reproduction and excretion. They put their cloacas together in what is called a "cloacal kiss" and the male passes his sperm to the female this way to fetilize her eggs. Some birds such as waterfowl (ducks, swans, etc) and ostriches actually do have a penis that is internal when not in use. This doesn't mean that their penis is small, it means that it can be saved inside until need. ;)
First of all, male "ducks" are called drakes. If the female is currently laying on her eggs trying to hatch them, it should be fine to leave the male around. If she's not take away the eggs from her. Unless they are fighting the male is fine.
21 to 30 days
