Why is My Duck Losing Feathers?
Let’s look at a few possible reasons why your duck might be losing feathers.
Molting Process
Ducks undergo annual molting.
This allows them to shed their old, worn feathers and start over.
Their feathers fall out all at once, but they regrow them in a matter of weeks.
In general, ducks molt twice a year, once in the middle of summer and again in the late winter or early spring.
Mallard Duck Family
The Mallard family includes all ducks that are not Muscovy ducks.
They come in a wide variety of breeds and names, such as Pekins, Indian Runner, Swedish, Silver Appleyard, Call, and Cayuga.
Different from Muscovy ducks, Mallards and their offspring go through the molting process at different times.
Most ducks in the mallard family are migratory, therefore mating and migration patterns dictate when they molt.
The climate, sex, age, and breed can all have an impact on how often and how quickly they molt.
There is a 1-2 month molting window.
Despite these classifications, ducks of the same breed can have vastly diverse molting schedules from one another.
Muscovy Duck Family
The females of this species of duck are the only ones who molt.
Female ducks regularly shed their feathers during a process termed the “nesting molt”, and the ducks then use the feathers to line their nests.
TMuscovy ducks molt between July and August.

Different Molting Kinds

Ducks undergo several distinct molts, an early Spring mold or a Summer molt.
Molting in Early Spring
The springtime molt generally only affects females and it is a more subtle molt.
You won’t notice too many feathers during this time. This can usually take place in the early spring or in the late winter time.
Molting in Summer
The major and main molt happens in the summertime and can last for 2 to 3 weeks. It’ll affect females and males.
Typically this can jumpstart a mating season as the males tend to love to show off their flashy new feathers.
You’ll definitely notice the loss of feathers as they will lose both their top feathers and down feathers.
During the molting season, both drakes and hens lose their downy undercoat.

Other Reasons for Ducks Losing Feathers

Several potential causes could be warning signs that something is wrong with your ducks.
Pecking
Pecking, or pricking, feathers are not an uncommon habit for birds.
Feather pecking is a behavior that is more habitual for the ducks and therefore other ducks have the possibility of developing this habit as well.
You want to make sure that the ducks stop this habit, but also it’s important to find out why they might be developing this habit.
- It could be just a habit, it could be because of irritation or dry skin, or even an infection.
- If you find that you can’t get the ducks to stop pecking and they are continually losing feathers, then it’s best to take them to a vet.
Environment Causes
The health of your birds can be negatively impacted by several environmental and management variables.
To keep your duck’s feathers in good condition, you should provide it with plenty of clean water and food, and try to keep pests like mites and lice at bay.
To get quality feathers, meat, and eggs from your ducks, you need to provide them with a healthy diet and a clean place to drink and bathe.

Stress can also cause ducks to lose feathers.
Reasons for this include – but are not limited to – severe weather, the spread of disease, a lack of medical care, and food and water.
Caring for your ducks properly is essential.
Be sure to give them adequate supplies and great living conditions for them to be happy and healthy.
