Baby duck care starts the moment ducklings arrive — they need warmth, water, and the right feed from day one to thrive. Ducklings require a brooder temperature of 90°F (32°C) in the first week, dropping by about 5°F each week until they’re fully feathered around 7-9 weeks old. They grow fast: a Pekin duckling doubles in size within 10 days and reaches near-adult weight by 8 weeks. This article covers brooder setup, feeding with the critical niacin supplement, common health checks, and a section specifically on Call duck care for anyone drawn to the miniature breeds. There’s also a beginner-friendly overview for first-time duck keepers.
Baby Duck Care and Feeding: The Niacin Rule You Cannot Skip
The single most important fact in baby duck care and feeding is niacin. Ducks need roughly twice the niacin (vitamin B3) of chickens, and a deficiency shows up fast — weak legs, bowed limbs, and joint problems as early as 2-3 weeks of age.
What to feed ducklings:
- Unmedicated chick starter (20-22% protein) with brewers yeast added — 1.5 tablespoons per cup of feed
- OR a dedicated waterfowl starter, if available locally
- Avoid medicated chick starter: amprolium is debated for ducklings, and many experienced keepers skip it entirely since ducks rarely get coccidiosis the way chicks do
Brewers yeast is the easiest fix, sold in most feed stores for around $10-15 per bag. Sprinkle it directly on the feed and mix it in. Nutritional yeast (from the baking aisle) works as a substitute in a pinch.
Ducklings also need access to water deep enough to submerge their entire bill — they push feed into their nostrils and need to flush it out. A small chick waterer is not deep enough. Use a 1-quart jar waterer or a shallow bowl at minimum, and expect a mess. Their brooder will get wet fast, so choose pine shavings or straw bedding and plan to refresh it every 1-2 days.
Baby Duck Health Care: What to Watch in the First Weeks
Good baby duck health care is mostly about prevention. A warm, dry brooder with correct feed and clean water handles 90% of problems before they start.
Daily health checks for ducklings:
| Sign | Healthy | Concern |
|---|---|---|
| Activity | Active, curious, running | Huddling alone, lethargic |
| Legs | Straight, walking normally | Bowed outward, stumbling |
| Eyes/nostrils | Clear, no discharge | Crusty, swollen |
| Droppings | Firm, greenish-brown | Watery, bloody, green paste |
| Feathers | Clean, drying quickly | Wet, matted, dull |
Niacin deficiency is the top duckling health issue. If you see a duckling stumbling or sitting back on its hocks at 2-3 weeks, increase the brewers yeast dose immediately and consider a niacin-only supplement (100 mg niacin per gallon of drinking water for a week).
Aspergillosis — a fungal lung infection from moldy bedding — is the second most common killer. It presents as open-mouth breathing and gasping. The fix is prevention: keep bedding dry and replace it before it smells musty. There’s no practical home treatment once a duckling is symptomatic.
Pasty vent (feces stuck over the vent opening) can affect young ducklings. Gently clean with a warm damp cloth — don’t pull. It usually resolves by week 2.
When to call a vet: Labored breathing, seizure-like tremors, persistent bloody droppings, or a duckling that stops eating and drinking despite warmth and correct feed. Avian vets familiar with waterfowl are the right call — not all small-animal vets are.
Call Duck Care: Brooding the Miniature Breeds
Call duck care follows most of the same rules as larger breeds, with a few important differences driven by their tiny size. Calls are bantam ducks — adults weigh only 1.5-2 lbs, and ducklings are correspondingly small. A day-old Call duckling is roughly the size of a golf ball.
What changes with Calls:
- Temperature regulation is harder: small bodies lose heat faster. Keep the warm end of the brooder at 92-93°F for the first week, and watch closely that ducklings can always move away from the heat lamp.
- Waterers must be shallower. A deep chick waterer can drown a Call duckling in the first two weeks. Use a very shallow dish (1 inch depth) with marbles in it to prevent submersion.
- Calls reach sexual maturity at 5-6 months — similar to larger breeds — but they are seasonal layers, producing 25-75 eggs per year.
- Call ducks fly well. Unlike Pekins or Rouens, Calls are not too heavy to get airborne. Plan for wing clipping or covered runs if you want to keep them.
Call duck care also demands the same niacin supplementation as any other duckling. Don’t skip brewers yeast because they’re small — the requirement per unit of body weight is the same.
Duck Care for Beginners: Building the Right Setup
For first-time keepers, duck care for beginners really comes down to four things: a safe brooder, proper feed, a water source they can dunk their heads in, and a predator-proof coop.
Beginner brooder checklist:
- Plastic storage tote or cardboard box (at least 2 sq ft per duckling)
- Heat lamp or plate brooder — keep warm end at 90°F week 1, reduce 5°F each week
- Pine shavings or straw, 2-3 inches deep
- Non-slip surface under the bedding (rubber shelf liner works)
- Waterer deep enough for bill submersion — refresh twice daily
Ducks do not need a pond. A $10 rubber feed pan or kiddie pool gives them everything they need. What they do need is enough water to submerge their full head — this keeps their eyes and nostrils clean and healthy.
Duck care for beginners also means accepting that ducks are wetter and messier than chickens. Budget for more bedding changes and consider a wire-bottom section over a drainage area in the brooder to keep ducklings from sitting in wet litter all day.
By week 7-9, most breeds are fully feathered and ready to move outside if nighttime temperatures stay above 50°F. Muscovy ducklings feather out more slowly and may need 10-12 weeks.
Transitioning Ducklings to the Outdoor Flock
Once ducklings reach 6-8 weeks old, they can join adult ducks — but the introduction matters. Adult ducks will establish pecking order through chasing and bill-grabbing. Run ducklings in a separate pen adjacent to adults for 1-2 weeks so they can see and smell each other through wire before direct contact.
Predator pressure on young ducks is higher than on adults. Ducks don’t roost off the ground the way chickens do — they sleep on the ground, which makes them easier targets for raccoons and mink. Hardware cloth (not chicken wire) on all coop openings, and a fully enclosed floor or an apron buried 12 inches out, are the baseline. Lock ducks in the coop every night without exception until you know your yard’s predator load.
Conclusion
Baby duck care requires warmth, niacin-supplemented feed, and enough water for full bill submersion from the first day. Get those three things right and most ducklings raise themselves. Good baby duck care in the first two weeks sets the foundation for a healthy flock that lays reliably for 5-10 years.

Frequently Asked Questions
Can ducklings swim right away?
No. Ducklings hatched in an incubator lack the maternal oil coating that lets wild ducklings waterproof immediately. Limit swimming to short supervised sessions of 5-10 minutes in shallow, warm water (80-85°F) until they are 3-4 weeks old and preening regularly. Unsupervised swimming before that age risks chilling and drowning.
How many ducklings should I get at once?
Get at least two. Ducks are social animals and a lone duckling will stress vocalize constantly and fail to thrive without company. Two to four ducklings in a brooder is a comfortable starting group. If you plan to keep only one adult duck long term, reconsider — solitary ducks develop behavioral problems.
Do I need a drake to get duck eggs?
No. Hens lay eggs without a drake, just as hens lay unfertilized eggs without a rooster. A drake is only needed if you want fertilized eggs for hatching. If you do keep a drake, maintain a ratio of at least one drake to three or four hens — over-mating causes serious back and neck injuries to hens.
When do ducklings start laying eggs?
Most domestic breeds reach sexual maturity and begin laying between 5 and 7 months of age. Khaki Campbells and Welsh Harlequins tend to be earlier (5-6 months); Muscovy and larger meat breeds like Rouen may take 6-7 months. Day length triggers laying — ducks started in spring will often lay their first eggs by early autumn.
