Why 80% of Chick Death Happens in the First Seven Days — And How to Stop It
Aaron Vet Farms Ltd — Your Trusted Poultry Health & Management Partner
If you’re raising chicks — whether broilers, layers, or dual-purpose breeds — one statistic haunts every poultry farmer: up to 80% of chick mortality occurs within the first seven days of life. This early chick mortality not only affects productivity and farm profitability but also raises questions about welfare and management practices.
Why Do Most Chicks Die Within the First Week?
The first seven days of a chick’s life are its most vulnerable. During this period, chicks transition from yolk-fed embryos to fully functioning animals that must regulate their own body temperature, drink water, and digest feed properly.
Here are the main causes of 80% early chick mortality:
1. Poor Brooding Temperature
Chicks need a stable and appropriate brooding temperature from day one.
Ideal temperature: ~32–35°C (90–95°F) in the first week.
Too cold → Chicks huddle and starve.
Too hot → Chicks pant, dehydrate, and die.
Temperature fluctuations are a silent killer in many setups.
2. Inadequate Brooder Management
Improper brooder setup — such as poor ventilation, dirty litter, or lack of space — leads to stress and disease.
Overcrowding increases pecking, heat stress, and suffocation risks.
Damp or soiled litter fosters bacterial growth.
3. Dehydration and Lack of Water Access
Chicks must find and drink water within the first 24 hours.
Dehydration from lack of water leads to early mortality.
Water spillage and improper drinker height can prevent chicks from accessing water.
4. Starvation and Poor Feed Quality
Chicks have extremely limited energy reserves once hatched.
Chicks that don’t eat within the first 48 hours can die from starvation.
Low-quality starter feed lacking balanced protein, vitamins, and minerals weakens immunity.
5. Infectious Diseases
Common diseases contributing to early chick death include:
Coccidiosis
Salmonella
E. coli infections
Marek’s disease
These often spread quickly in crowded or poorly managed flocks.
6. Congenital Weakness & Hatchery Stress
Some chicks are born weak, dehydrated, or with deformities due to:
Poor egg handling
Inadequate incubation
High hatchery stress
These chicks struggle to compete for feed and water.
7. Poor Biosecurity
Uncontrolled access of pests, rodents, and humans with dirty footwear/clothing spreads pathogens into the brooding area.
How to Reduce Early Chick Mortality — Proven Strategies
The good news? Most early chick deaths are preventable with proper management. Here’s how to make sure your chicks thrive in the first seven days:
1. Master Brooding Temperature & Humidity
Temperature Guidelines:
Day 1–3: 32–35°C (90–95°F)
Day 4–7: Gradually reduce by 2–3°C (5°F)
Tips
Use reliable thermostats and backup heat sources Group chicks by age and avoid drafts Provide gradients so chicks can move to comfortable zones
2. Ensure Continuous Water Access
Water is life — especially for day-old chicks.
Best Practices:
Use chick drinkers, not adult nipples
Place waterers so chicks can easily see and reach them
Add electrolytes or vitamins in water during the first 48 hours
Check water temperature (room temp is ideal)
3. Provide High-Quality Starter Feed
Chicks need:
High protein (20–24%)
Easily digestible ingredients
Essential vitamins and trace minerals
Starter feed should be offered continuously and always visible.
Tip: Crumbles or fine pellets help newly hatched chicks eat more easily.
4. Implement Strong Biosecurity Measures
Prevent disease before it starts:
Footbaths at entry points
Clean and disinfect brooding areas
Wash hands and change clothes before handling chicks
Control rodents and insects
5. Keep the Brooding Area Clean
Clean, dry litter prevents:
Respiratory issues
Coccidia outbreaks
Bacterial infections
Replace bedding as needed and ensure proper drainage.
6. Use Preventive Health Protocols
Talk to a poultry vet (like our experts at Aaron Vet Farms Ltd) about:
Vaccination schedules (e.g., Marek’s, Newcastle)
Coccidiosis prevention
Probiotics and gut health boosters
Proper health planning significantly reduces mortality rates.
The Impact of Reducing Early Chick Death
Financial Benefits
Reducing early mortality:
Increases overall flock size
Improves feed conversion ratio (FCR)
Raises profitability per cycle
Welfare Benefits
Chicks that survive and thrive are:
More active
Stronger immune systems
Better performers as adults
Healthy chicks mean better growth, better eggs, and stronger birds.
Frequently Asked Questions (FAQs)
1. Why do most chicks die within the first 7 days?
Most chick deaths occur due to temperature stress, dehydration, lack of feed intake, infectious diseases, and poor brooding management. Up to 80% of mortality happens in this period because chicks are transitioning from yolk nutrition to independent feeding.
2. What temperature should chicks be in the first week?
Maintain 32–35°C (90–95°F) for the first three days and reduce gradually by a few degrees each day, ensuring chicks can move to cooler or warmer zones.
3. How can I keep my chicks from dying?
Focus on proper brooding temperature, clean water, high-quality starter feed, good ventilation, and strict biosecurity. Regularly monitor chick behavior and consult a vet for vaccination and health checks.
4. Is dehydration a common cause of chick death?
Yes — if chicks don’t find water quickly after hatching, they can dehydrate and die. Place waterers where they are easily seen and accessible.
5. Can infections be prevented?
Good hygiene, proper litter management, vaccination, and limiting access of pests help prevent common bacterial and parasitic infections that kill chicks.
6. Should I use supplements in chick water?
Electrolytes and vitamins in the first 48 hours can boost chick resilience, but use them according to veterinary guidance to avoid overdosing.
Final Thoughts
Early chick mortality doesn’t have to be a “fact of life” on your poultry farm. With the right brooding temperature, water and feed management, biosecurity, and veterinary support from Aaron Vet Farms Ltd, you can dramatically reduce chick deaths in the first week.
Healthy chicks = healthier flocks, higher productivity, and a more profitable farm.
