Raising healthy chicks is the dream of every poultry farmer. But sometimes, despite your best efforts, your chicks grow too slowly — or stop growing altogether. Poor growth means weaker birds, reduced meat or egg production, increased risk of disease, and serious losses for smallholders and commercial farmers alike.
In this blog, we'll explore the top 23 reasons why your chicks may be growing slowly — and exactly what you can do about it. From feed quality to chick genetics, brooder temperature to common infections, we’ll break down every possibility with practical fixes you can apply starting today.
Let’s dive in. 🕵️♂️🐤
📍 1: Understanding Chick Growth Basics 🧬
Before jumping into problems, we need to know what “normal” chick growth looks like.Healthy chick growth means your birds reach market or laying weight at the expected time. This not only ensures profitability but also lowers feed conversion ratio (FCR) — a critical metric in poultry farming.
📊 Normal Growth Benchmarks:
- A healthy broiler should gain about 40–50 grams per day after the first week
- A layer chick should double its hatch weight by week 2 and triple by week 4
- By week 4, broilers should weigh around 1.1–1.2 kg and layers around 250–300g
Growth is influenced by:
🧬 Genetics (broiler vs. layer vs. desi breeds)🥣 Feed (protein, energy, vitamins)
🌡️ Environment (temperature, lighting, hygiene
) 🦠 Disease exposure
📏 Stocking density and management
🔥 2: 23 Reasons Why Chicks Grow Slowly — and How to Fix It
❄️ 1. Poor Brooder Temperature Chicks can't regulate their body temperature during the first week of life. If the brooder is too cold, they use up feed energy just to stay warm, leaving little for growth. Symptoms: Huddling, loud chirping, piling on each other.
💪 Fix: Maintain 32–35°C during the first week and reduce by 2–3°C each week thereafter. Use an accurate thermometer, and observe chick behavior to adjust heat sources accordingly.
🔥 2. Excessive Heat Overheating causes panting, drooping wings, and dehydration.
💪 Fix: Use shades, fans, and infrared bulbs. Avoid direct sun and monitor regularly.
🦠 3. Low Protein in Starter Feed Protein deficiency leads to weak muscles, poor organ development, and dull feathers.
💪 Fix: Feed 20–24% protein starter for broilers, 18–20% for layers. Use balanced commercial feeds.
🍼 4. Low Energy Levels Energy is required for every metabolic function. Without it, growth slows.
💪 Fix: Include corn, fats, or oilseed cakes in proper amounts. Keep energy levels at 2800–3000 kcal/kg.
🦤 5. Mycotoxins in Feed Fungal contamination from poor storage leads to liver damage and suppressed immunity.
💪 Fix: Store feed in cool, dry conditions. Discard any musty-smelling or clumpy feed. Add toxin binders like zeolite or bentonite clay.
🦞 6. Coccidiosis Infection This common disease damages intestinal lining.
💪 Fix: Keep litter dry. Use coccidiostats or vaccines. Rotate anticoccidials to prevent resistance.
💩 7. Worm Infestation Worms drain nutrients and impair digestion.
💪 Fix: Deworm using piperazine or albendazole every 30–45 days. Use clean, dry bedding.
🥸 8. Viral Infections (Newcastle, Gumboro, Marek’s) Viruses lower appetite and can permanently damage internal organs.
💪 Fix: Stick to a strict vaccination schedule. Isolate sick birds quickly.
🐤 9. Weak Day-Old Chicks Hatchery problems can lead to poor immunity and stunted growth from day one.
💪 Fix: Buy only from certified hatcheries with transparent vaccination and biosecurity programs.
💦 10. Water Contamination Dirty water spreads bacteria and parasites.
💪 Fix: Sanitize drinkers daily. Use chlorine or potassium permanganate to clean.
❄️ 11. Cold Drinking Water Chilled water causes digestive shock.
💪 Fix: Slightly warm water during cold seasons. Encourage post-feeding hydration.
🔦 12. Improper Lighting Schedule Erratic lighting disrupts feeding rhythm.
💪 Fix: Use 20–22 hours of light daily in week 1, reduce gradually.
🐔 13. Overcrowding Too many chicks in a tight space leads to competition, bullying, and stress.
💪 Fix: Maintain 1 sq. ft per chick by week 4. Increase space as they grow.
🥴 14. Handling Stress Excessive or rough handling spikes stress levels.
💪 Fix: Handle gently. Avoid unnecessary noise and commotion.
💨 15. Poor Ventilation High ammonia levels affect lungs and reduce appetite.
💪 Fix: Improve airflow using windows, exhaust fans, or chimneys. Monitor litter for moisture.
🧪 16. Vitamin Deficiencies Deficiencies cause deformities, poor bone formation, and immunity issues.
💪 Fix: Give multivitamins from day 1. Rotate supplements for broad coverage.
❌ 17. Interrupted Water Supply Even brief interruptions reduce feed intake.
💪 Fix: Ensure constant water availability. Use float valves or automatic systems.
⏱️ 18. Irregular Feeding Schedule Missed meals cause inconsistent growth.
💪 Fix: Feed 4–5x daily in first 2 weeks, taper to 2–3x later.
🌾 19. Poor Feed Mixing Improper mixing creates nutrient gaps.
💪 Fix: Use mechanical mixers for large batches. Measure ingredients precisely.
🦴 20. Bone Disorders (Rickets) Caused by calcium-phosphorus imbalance or lack of D3.
💪 Fix: Add DCP, oyster shells, or bone meal. Supplement with D3.
🚚 21. Transport Stress Stress from long journeys leads to high mortality.
💪 Fix: Minimize travel time. Provide glucose/electrolyte water on arrival.
🌍 22. Harsh Weather Cold, heat, humidity — all affect growth.
💪 Fix: Use heaters, foggers, or curtains as needed. Monitor climate regularly.
❌ 23. Feed Withdrawal After Hatch Delaying feed after hatch reduces enzyme development.
💪 Fix: Provide feed and water within 6 hours. Use chick booster formulas early.
🔬 3: How to Track Chick Growth Like a Pro
- Weigh 10 random chicks weekly
- Compare with breed standards
- Record feed intake and mortality
- Watch for patterns in low-weight birds
Keep detailed logs to track FCR (feed conversion ratio) and performance.
🔬 4: Breed-Specific Growth Tips 🐓 Broilers (Cobb, Ross, Hubbard):
- Fast growers. Focus on high-protein feed, lighting, and litter hygiene.
🍳 Layers (Lohmann, ISA Brown):
- Emphasize early bone development, gut health, and balanced lighting.
🐔 Desi/Native Breeds (Kadaknath, Aseel):
- Slow growth, strong immunity. Allow free-range. Use herbs like tulsi and neem.
🥚 Crossbreeds (Kuroiler, Rainbow Rooster):
- Balanced needs. Manage transitions in feed and space as they grow.
💪 Quick Tips for Faster Chick Growth
- Start multivitamins on day 1
- Use probiotics or yeast for gut health
- Maintain 3–4 inch dry litter depth
- Prevent wet spots
- Stick to strict lighting and feeding routines
- Observe birds daily for any unusual behavior
❓ FAQs: Chick Growth Problems
Q1: Why are some chicks smaller than others?A: Genetic differences, poor feeder access, or early disease. Separate small chicks and monitor closely.
Q2: Can cold nights slow chick growth?
A: Yes. Chicks will eat less and use energy to stay warm. Insulate and monitor night temperatures.
Q3: Is commercial feed better than homemade?
A: Usually yes, due to consistent nutrient formulation. If homemade, get it tested.
Q4: Should I give glucose or sugar water?
A: Yes, during the first 48 hours post-hatch or after stress.
Q5: What herbal remedies help chick growth?
A: Garlic boosts immunity, turmeric aids digestion, tulsi fights infection. Use with care.
