Baby chickens should be kept in temperatures between 90-95°F for the first week; above 100°F can lead to heat stress and potential health issues.
Raising baby chickens requires careful temperature management. Chicks can’t regulate their body temperature effectively until they’re fully feathered at 4-6 weeks old. Understanding heat thresholds and cooling strategies is crucial for their survival.
Critical Temperature Thresholds for Chicks
Baby chickens have specific temperature needs that change as they grow:
| Chick Age | Ideal Temperature | Danger Zone | 
|---|---|---|
| Week 1 | 95°F (35°C) | Above 100°F (38°C) | 
| Week 2 | 90°F (32°C) | Above 95°F (35°C) | 
| Week 3 | 85°F (29°C) | Above 90°F (32°C) | 
| Week 4+ | 75-80°F (24-27°C) | Above 85°F (29°C) | 
Humidity’s Impact on Heat Tolerance
Humidity dramatically affects how chicks experience temperature. According to PoultryDVM research, high humidity prevents effective evaporative cooling through panting. A 90°F day with 80% humidity feels like 113°F to chickens.
Signs of Heat Stress in Baby Chicks
Watch for these critical warning signs:
- Excessive panting with beaks open wide
 - Wings held away from body
 - Lethargy and reluctance to move
 - Pale or purple combs/wattles
 - Diarrhea or watery droppings
 - Loss of appetite but increased water consumption
 
Cooling Strategies for Hot Weather
Brooder Modifications
For indoor brooders:
- Raise heat lamps higher to reduce intensity
 - Create a thermal gradient – warm on one side, cool on the other
 - Place frozen water bottles wrapped in towels in the brooder
 
Outdoor Solutions
When moving chicks outside like in introducing to new coops:
- Provide deep shade with proper airflow
 - Use misters or shallow water pans for evaporative cooling
 - Offer electrolyte-enhanced water (1 tsp salt + 1 tsp sugar per gallon)
 
Special Considerations by Breed
Some breeds handle heat better than others:
Heat-Tolerant Breeds
- Leghorns
 - Egyptian Fayoumis
 - Naked Neck Turkins
 
Heat-Sensitive Breeds
- Brahmas (heavy feathering)
 - Cochins (dense plumage)
 - Silkies (reduced heat dissipation)
 
As noted in University of Kentucky research, feathering density directly impacts heat tolerance.
Emergency Cooling Measures
If chicks show severe heat stress:
- Immediately move to cooler area
 - Dip feet in cool (not cold) water
 - Offer electrolyte solution
 - Use a fan to create gentle airflow
 
Long-Term Heat Management
For sustained hot weather:
- Adjust feeding times to cooler morning/evening hours
 - Provide high-moisture treats like watermelon
 - Consider advanced cooling techniques
 - Install proper ventilation in permanent coops
 
Monitoring Tools
Essential equipment includes:
- Digital thermometer with humidity readout
 - Infrared temperature gun for spot checks
 - Weather station for outdoor conditions
