Creating a Safe, Comfortable Home for Your Baby Birds

Brooder Basics That Matter Most
By Drs. Julie Ashley and Blayne Mozisek
Starting your babies off right means creating a brooder environment that supports their warmth, comfort, and natural development. Three of the most important factors—temperature, bedding, and ventilation—set the foundation for a thriving flock.
**Temperature Gradient: How Poultry Babies Find Their Comfort Zone
- Newly hatched babies are poikilothermic, meaning they cannot regulate their own body temperature. For the first 7–10 days, they rely on external warmth.
- A centrally located heat source creates a warm “hot spot” in the brooder, with cooler areas further away. This natural temperature gradient lets chicks choose their comfort zone.
- Healthy babies spread loosely in a ring around the warmest spot—your best sign the setup is correct.
- Heat source options: heat lamps, heat plates, or radiant panels. Always secure them safely.
- TPD tip: Heat lamps are simple, affordable, and effective. When positioned correctly, chicks form a ring about 12–18 inches in diameter.
- Too cold: babies huddle directly under the lamp → lower it.
- Too hot: babies scatter to the edges → raise it.
Bedding: Setting the Right Foundation for Healthy Babies
- Best choice: use pine shavings (large flake for waterfowl helps prevent ingestion) or coarse pine sawdust—soft, absorbent, low dust, and safe.
- Consistency matters: keep babies on pine bedding for the first 21–28 days.
- If you have chicks vaccinated for coccidiosis, they must recycle the vaccine at least three times (picking it up from droppings) to build lasting immunity.
- Avoid unsafe materials: cedar may release harmful compounds and hardwood shavings often carry Aspergillus spores, which can lead to fungal pneumonia in baby poultry .
- Helpful tip (days 1–7): add paper plates with feed in the brooder (we’ll cover feed in article 3 of this series). Chicks naturally forage in them, boosting activity and feed intake.
- Droppings matter: chicks need some exposure to their own droppings to seed healthy gut flora and support coccidiosis vaccine cycling. The environmental goal inside the brooder isn’t sterility—it’s a balanced environment that’s comfortable, supportive, and not overcrowded.
- Moisture is important for chicks:
- For coccidia (cocci) to sporulate and complete the vaccine cycle, they need some moisture.
- Bedding that is powder-dry is not ideal.
- The correct moisture level should allow you to press a handful of bedding firmly and form a loose ball that just holds its shape before falling apart. It should not be wet or drip moisture when squeezed firmly.
- Jump-starting gut health:
- If adding chicks to an existing flock, sprinkle about 1 cup of bedding—including fresh droppings—from your healthy adult flock into the chicks’ bedding for every dozen chicks. This helps seed the chicks’ gut with beneficial microflora.
- If you’re concerned or unsure of your existing flock’s health—or starting a brand-new flock—use a live-culture probiotic in the starter feed when you bring baby poultry home to help establish a strong, balanced gut flora.
**💡 Myth buster:
Myth: A spotless, sterile brooder is the healthiest environment.
Truth: Chicks actually need controlled exposure to droppings to develop strong gut health and immunity.
Ventilation: Fresh Air Without Drafts
- Poultry babies do best in a well-ventilated room—not sealed up tight.
- Proper ventilation prevents damp bedding, strong odors, and respiratory issues.
- Humidity matters: keep the brooder room around 60% humidity.
- Helps prevent the bedding from drying out too much.
- Keeps babies from becoming dehydrated in the warm brooder environment.
- Warning signs: ammonia smell, wet litter, or babies snicking (sneezing/coughing).
- Chicks vaccinated for respiratory viruses, like infectious bronchitis or New Castle Disease, will likely develop a mild reaction to the vaccine - this is normal and this reaction (snick/sneezing) should dissipate as they clear the vaccine virus - no treatment is necessary.
✅ By focusing on these three essentials—steady warmth, safe bedding (with the right moisture for chicks), and fresh room air with balanced humidity—you give your babies the best possible start, setting the stage for a healthy, thriving flock.
🧰 Your turn: What’s been the biggest challenge for you in setting up a brooder — keeping the right temperature, finding the right bedding, or getting ventilation just right?
