Sudden Drop in Feed and Water Intake: The First Silent Signs of Sick Chickens.
If you want to know what’s happening inside a chicken, watch the feeder and drinker. Birds don’t stop eating or drinking for no reason.
Here’s what you’ll notice:
- They stand near the feeder but barely peck.
- Water consumption drops even when the weather is hot.
- They eat slowly or show zero interest in the feed.
A drop in feed or water intake often signals:
- Early infection (like coccidiosis or bacterial diseases)
- Heat stress
- Poor-quality feed
- Digestive discomfort
- Water contamination
When intake goes down, body weight, immunity, and productivity crash. If you catch this early, you can stop bigger disasters from happening.
Immediate action you can take as a poultry farmer:
Check water lines, feed quality, and heat levels, and consider isolating weak birds. Record changes daily; numbers don’t lie.

Signs of Sick Chickens Start from Unusual Droppings: Your Birds Are Speaking Through Their Poop
Chicken droppings tell powerful stories. If you pay attention, you’ll detect problems long before they escalate.
Watch out for:
- Bloody droppings: Possible coccidiosis
- Green watery droppings: Fever or bacterial infection
- Foamy yellow droppings: Gut irritation or feed changes
- White pasty droppings: Stress, dehydration, or kidney issues
Normal droppings should be brownish with a white cap. When the shape, colour, or smell changes drastically, consider it a warning message from the flock.
Immediate action to take:
Clean and disinfect the pen, check feed ingredients, improve water quality, and seek veterinary guidance if the abnormal droppings persist.

Red flags include:
- Pale comb: anaemia or parasitic problems
- Purple comb: respiratory issues or poor oxygen supply
- Shrunken comb: weakness or dehydration
- Swollen eyes: respiratory disease
- Tearful or watery eyes: irritation or infection
If one bird shows it, others may soon follow. This is a crucial moment for farmers to act fast.
Improve ventilation, check ammonia levels, isolate affected birds, and clean water lines to prevent respiratory irritation.
