Mallard Call Duck: Health, Temperament, Care & Costs

Mallard Call Ducks, usually called Call ducks, are one of the smallest domestic duck breeds. They were developed from mallard-type ducks and are known for their round bodies, short bills, and very loud, high-pitched voices. Hens are usually noisier than drakes. Their compact size makes them appealing to many pet parents, but they are still true waterfowl with messy habits, social needs, and outdoor housing requirements.

Temperament is often described as alert, active, and people-aware. Many Calls become friendly with regular, calm handling, especially when raised in pairs or small groups. They tend to do best with other ducks rather than alone. A single duck can become stressed, vocal, and harder to manage.

These ducks are better suited to a secure backyard setup than indoor life. They need predator-safe shelter, daily access to clean drinking water deep enough to rinse their nostrils, and room to walk, forage, and bathe. Their small size can make them more vulnerable to predators and rough flock dynamics, so housing design matters.

For many families, the biggest surprise is not temperament but care intensity. Call ducks are charming and entertaining, yet they need regular cleaning, species-appropriate feed, and access to a vet who is comfortable treating birds or poultry.

Call ducks are generally hardy when their environment and diet are appropriate, but they are prone to several preventable problems. Pododermatitis, often called bumblefoot, can develop when ducks spend too much time on wet, dirty, rough, or poorly cushioned surfaces. Early signs may include limping, swelling, redness, or a scab on the foot pad. Because ducks hide illness well, mild foot pain can become a deeper infection before a pet parent notices it.

Nutrition-related disease is another common concern. Waterfowl have different needs than chickens, and feeding chicken feed, bread, or mostly treats can contribute to poor feather quality, swollen joints, weak growth, and obesity. Ducklings are especially sensitive to niacin deficiency, which can cause leg weakness and enlarged hock joints. Adult ducks can also develop obesity and fatty liver changes when activity is limited and calorie-dense treats are common.

Female ducks may face reproductive problems such as egg binding or laying-related stress, especially if they are overweight, nutritionally imbalanced, or laying heavily. Respiratory disease can also occur, including fungal and bacterial problems in damp, poorly ventilated housing. Any duck with open-mouth breathing, tail bobbing, blue discoloration, weakness, sudden drop in appetite, or trouble walking should see your vet promptly.

In backyard flocks, infectious disease risk also matters. Domestic ducks can be exposed to parasites, bacterial infections, and serious viral diseases such as duck viral enteritis, and contact with wild waterfowl raises biosecurity concerns. Good sanitation, dry bedding, clean water, and limiting wild bird contact can lower risk, but they do not replace veterinary guidance when a duck seems ill.

The purchase cost for a Mallard Call Duck is usually only a small part of the long-term commitment. In the U.S. in 2025-2026, many hatchery or farm-source Call ducklings fall around $15-$40 each, while sexed juveniles, uncommon colors, or exhibition-quality birds may run $50-$150+ each. Because ducks are social, most pet parents should plan for at least a pair rather than one bird.

Basic setup costs are usually the biggest first-year expense. A secure coop or night house, predator-proof run, water tubs or a small pond setup, feeders, and bedding commonly add $250-$900+ depending on whether you build or buy. Ongoing routine care for two Call ducks often lands around $30-$60 per month for feed, bedding, and water-area maintenance, or roughly $354-$720 per year before veterinary care.

Veterinary costs vary widely by region and by whether you have access to an avian or poultry-experienced clinic. A wellness exam may cost about $70-$150, fecal testing often $25-$60, and treatment for common problems like bumblefoot, parasites, or minor wounds may range from $120-$400+. Emergency visits, imaging, hospitalization, or surgery for reproductive disease can move into the $300-$1,000+ range.

It helps to think in tiers. Conservative care focuses on safe housing, prevention, and early vet attention before a problem escalates. Standard care adds routine exams and diagnostic testing when needed. Advanced care may include radiographs, lab work, surgery, or referral-level avian treatment. The best plan depends on your duck, your goals, and what resources are available in your area.

Mallard Call Ducks should eat a species-appropriate duck or waterfowl feed, not chicken feed as a default. Merck Veterinary Manual notes that growing waterfowl need a higher-protein starter diet, and after about 12 weeks most adult waterfowl do well on a maintenance ration with roughly 14-17% protein and adequate vitamins and minerals. During breeding or laying, nutritional needs may shift, so it is smart to review the diet with your vet.

Ducklings need special attention because waterfowl are more sensitive than chickens to niacin deficiency. A balanced duck starter is the safest foundation. Bread, crackers, and large amounts of corn or lettuce are not complete diets and can contribute to nutrient deficiencies, poor growth, swollen joints, and foot problems. Treats should stay limited and should never replace the main ration.

Adult Call ducks also benefit from safe foraging, leafy greens, and access to clean water while eating. Ducks need water deep enough to rinse their nostrils and help them swallow feed comfortably. Feed should be kept dry and fresh, and moldy feed should be discarded right away.

If your duck is overweight, laying frequently, or has a history of leg or foot issues, ask your vet to review body condition and ration details. Small ducks can still become obese, and extra body weight can worsen mobility and reproductive stress.

Call ducks are active little foragers. They do best with daily space to walk, dabble, explore, and interact with other ducks. Even though they are small, they should not be treated like low-maintenance ornamental birds. Regular movement supports muscle tone, foot health, and healthy body condition.

A secure outdoor run with varied footing works well for many households. Grass, clean soil, pea gravel around water stations, and dry resting areas can help reduce mud buildup and lower the risk of foot problems. Access to a tub, trough, or pond area encourages natural bathing and preening behavior, but the water source needs frequent cleaning.

Mental activity matters too. Ducks enjoy foraging opportunities, scattered greens, supervised yard time in safe areas, and flock companionship. Bored or isolated ducks may become louder, more stressed, or less active. Because Call ducks are small and vulnerable, free-ranging should only happen where predator risk is truly controlled.

If your duck suddenly becomes reluctant to walk, lags behind flock mates, sits more than usual, or seems off balance, that is not normal exercise fatigue. It can point to pain, nutritional disease, injury, or illness, and your vet should guide the next steps.

Preventive care for Mallard Call Ducks starts with housing. They need a dry, draft-protected shelter at night, good ventilation, clean bedding, and strong predator protection. Wet, dirty environments increase the risk of foot disease, parasites, and respiratory problems. Water areas should be cleaned often enough that ducks are not standing in foul water all day.

Biosecurity is especially important for backyard waterfowl. Limiting contact with wild birds, cleaning boots and equipment, quarantining new birds, and watching closely for sudden illness can help reduce disease spread. Ducks can carry or develop serious infectious disease, and outbreaks may move quickly through a flock.

Routine observation is one of the most useful tools a pet parent has. Check appetite, droppings, gait, feather condition, foot pads, and breathing every day. Female ducks should also be monitored for changes around laying, including straining, weakness, or a swollen abdomen. Early changes are often subtle.

A relationship with your vet matters even if your ducks seem healthy. Ask whether the clinic sees ducks or can refer you to an avian veterinarian. Wellness exams, fecal checks when indicated, prompt wound care, and nutrition review can all support a longer, healthier life. See your vet immediately for breathing trouble, inability to stand, severe lethargy, bleeding, or suspected egg binding.
