Ducks:
Migrate, aquatic animals that feed on plants, seeds, and insects. Fly at up to 80kph. Live in large flocks in pairs for breeding, with elaborate courtship behaviours, with very sensitive beaks. They are water birds-evolved to eat, swim, dive, clean, and play in water. They live naturally up to 20 years.

Well, not in this world. instead of the life they could have, those birds cannot fly, cannot swim and some can barely walk. They never see water, except in their drinkers, they cannot preen properly and barely keep warm.
Without water, their lives have no meaning.

About 13 million ducks are raised for slaughter and egg production. In the meat industry, they live only 7-10 weeks, and many will be fully conscious when their throats are cut. All across the world, ducks are being driven off ponds and into intensive sheds.
Up to 85,000 ducks are jammed into a shed, faeces-sodden litter – filthy conditions that cause them painful ammonia burns. Naturally, they would keep themselves spotlessly clean. In the stinking sheds, the filth just builds up on them.

There are two types of farmed ducks: the Mallard (Anas platyrhynchos) and the Muscovy duck (Cairina moschata). The Mollard, also known as Moulard, is used for the infamously cruel production of Foie Gras.

Most floor designs in total-confinement duck housing use either wire mesh, or litter and Keeping ducks on wire results in abrasions, bruises and tears in the area of the hock, shank, or foot pad. Painful Staphylococcal and streptococcal joint infections are the common result. Those ducks suffer just from being alive. Any natural need is deprived from them, and it hurts them just to stand or sit.
Worse than wire floors are slatted floors, which increase leg deformities.

Thousands of these miserable, essentially wild, dejected creatures struggle around the huge dark stinking dirty full of ammonia barren shed, which they are incarcerated day after day. They waddle through their piled-up sodden excreta, denied their basic natural medium.
There is no sun, no wind, and no rain to run off their backs – just constant artificial light. Unsurprisingly, many become diseased and die in the crowded sheds; they barely walk, some fall on their backs and cannot turn back over, get knocked over by others and are often unable to manage themselves. Even when put back on their feet they take some time to reorient themselves. In the packed conditions of a shed, stranded ducks go unnoticed. Many ducks are trodden underfoot get beating by other ducks and die from severe injury or starvation. At the back of many farms, there are bins full of dead ducklings.

They live under huge pressure, and because of the stress, those miserable ducks, pull, and eat feathers from one another, either before or after death, and even their own feathers.
Many females harass males by nipping their penis, sometimes to the point of irreversible mutilation.

Instead of dealing with the real problem – exploitation of those ducks in the most disgraceful conditions by confining them in overcrowding sheds, lack of water and all their natural needs, suffer from day 1 to death – those Humans are debeaking (bill trimming) them.

Obviously, the duck's bill, including the very tip, is richly innervated – supplied with nerves – with sensory receptors, so this mad procedure is one of the most traumatic experience those ducks endure in their short miserable life. Even if the wounds heal, there is no functional substitution for that loss.

In the wild, the female duck lays 8 eggs two to three times a year. In the farm, the ducks were genetically altered to produce more eggs and meat, those birds are regarded as mere machines. Mother ducks have been bred to produce 100% MORE DUCKLINGS than 5 years ago, and they never got to bond with her babies. One producer said they have produced a 'superduck', which lays up to 275 eggs a year, more than ten times of what she had evolved to lay.

This huge amount of eggs leaves her with weak fragile bones, which snap easily, since she provides shells around her eggs from her body calcium. The duck egg industry is following the battery egg industry where 90 percent of birds have broken bones by the time they are murdered in the slaughterhouses.

This genetic manipulation caused a disease called Egg Peritonitis. Many ducks die in agony as a result of it. Their ovaries became inflamed and their reproductive tracts ruptured. The deaths that followed were racked with enormous pain. Many bodies remained littering the floor of the duck prison, since often only 1 person bothers to 'look after' those ducks. From day one, ducks in natural state displayed an intense interest in water and spend most of their waking hours swimming and investigating streams and puddles.

Duckling in the industry never knows anything better than a shallow drinking or, worse, systems like water nipples that do not allow immersion of the head.
Ducks denied water to swim, although naturally they spend most of their time in water..

The lives of these essentially aquatic birds consist of pushing their way through the mass of other birds to get to pelleted food and water nipples or other drinking points. The ducks are too heavy to fly, and had been fed and bred in such a ruthlessly way that they could not walk without severe pain.

In nature, they like to spend a lot of time preening, and it's vital to their health that they can immerse themselves in water – or at least to dip their heads under. They like to keep themselves spotlessly clean.
In farms, ducks are denied these natural cleansing activities, some of the breeders even added an enzyme to the feed of ducks to reduce the amount of water they drink, so they won't splash the water around and over their bodies.
This leads to poor feathers, difficulty in keeping warm, eye problems, and even blindness since they not being able to rinse their eyes in water.

Since they are a breeding stock, in the egg industry they were made to endure 'forced moulting'. All feed was removed until they lost a third of their bodyweight!
During this time, they lost their feathers and become a bald ducks.
Those ducks, which, by nature preening and cleaning, now lost another reason to live.
Many die, others get sick. The result is that the survivals are able to endure one more egg-laying cycle before they are murdered.

The ducklings in the meat industry who manage to endure their dire conditions for 7 weeks, along with the egg laying ducks are then brutally slaughtered. They are stuffed into crates and transported to the slaughterhouse. During this manhandling and crushing, they having their legs broken or receive other injuries. They are then grubbed and hung upside down by their legs (broken or not) on a conveyor system. Their heads are supposed to be dipped into an electrical water bath. The majority of the ducks are not stunned at all, and are knifed fully conscious. The ducks try to lift their heads away from the water bath. Wouldn't you? From their point of view, they see what is happening to those going before them; they do not want to drown in water. They want to swim in it feet first.
Ironically and of course crazy, denied water all their lives, then forced into it - head first!
