I raise ducks every year. If I don't hatch them out in the incubator, the mother ducks will do it themself. There is nothing much cuter then the mother duck leading the way, her babies behind her, and the drake, (dad) duck following behind to keep the duckling in line. They make happy noises when they are walking around looking for bugs and grass to eat. The eggs are larger than chicken eggs and they make the cake rise higher and taste better. The farm raised ducks have all dark meat and some people prefer the taste over chicken.
One year, a duck hatched her babies in my son's dog's house. After they hatched, she would let Apollo babysit them. The poor dog even had them swimming in his water dish. The next year, he moved to a different doghouse because he had around 7 ducks bothering him.
There are many different breeds of ducks and some even have feathers on their head like a bonnet. You just throw grain out for them when they are grown, and give them a wading pool to keep clean. Even during a snowstorm, they would rather sit out in the cold then go into a shelter.
I have the regular ducks such as mallards, but also Muscovies, which is not a true duck. Muscovies come from South American and are known as perching birds. The hens will fly high to sit in a tree. They don't have oil glands like a regular duck and can drown if they stay in the water too long. These are the ones that get red bumps on their heads.
I enjoy watching the different animals interact with each other. Every duck has it's own personality and beauty.
