Winter and rainy seasons may look calm from outside, but inside the shed, birds start feeling stress immediately. Temperature falls, humidity rises, and litter becomes wet faster. Farmers usually notice the impact only when weight gain drops or activity slows, but the stress begins much earlier.
Cold Weather Slows Growth Without Warning
During winter, birds burn more energy to stay warm. Even a small drop in temperature makes them huddle, reduce movement, and eat less. Feed is used for body heat instead of growth. This silent stress results in slow weight gain and weak uniformity across the flock.
Rainy Days Increase Humidity and Breathing Stress
Rain increases moisture in the environment, causing humidity inside the shed to rise. Birds struggle when the air becomes heavy, and breathing becomes uncomfortable. Litter gets soft, ammonia builds up quickly, and feed intake drops day by day — even when everything looks normal.
Wet Litter Becomes the Hidden Reason for Loss
Both winter and rainy seasons push litter to get wet overnight. Birds avoid resting on wet patches, stop moving freely, and reduce feeding behavior. Wet litter silently reduces performance, and the flock ends up below the target weight without any visible early signals.
Small Daily Losses Become Big End-Cycle Damage
Many farmers consider small daily mortality “normal” during winter or rain. But these small losses are early climate warnings — cold stress, humidity spikes, or poor ventilation. Mortality never increases suddenly; it grows when early corrections are missed.
Why Climate Control Matters More Than Season
Performance drops not because of the season, but because climate inside the shed changes faster than farmers react. When farmers keep temperature stable, control humidity, improve ventilation, and maintain dry litter, birds grow smoothly even in tough weather conditions.
Conclusion: The Season Isn’t the Problem — Invisible Climate Stress Is
Winter and rainy weather do not reduce broiler growth by themselves. The real problem is the small, unnoticed climate shifts inside the shed that quietly impact feed intake, activity, and weight gain. When farmers focus on daily climate balance, birds respond quickly and maintain target performance — no matter the season.
