Birds start drinking less a day or two before they stop eating and turn dull. If you record water use every day, you see disease or a breakdown before it shows in the house. It’s the cheapest early warning system there is.
How much birds drink
At around 20 °C birds drink about 1.6–2 times as much water as they eat feed by weight. In the heat, 3–4 times as much. Guidelines per bird per day:
| Bird | Water per day at 20 °C |
|---|---|
| Laying hen | 200–300 ml |
| Broiler at 2 weeks / at 6 weeks | 100–150 ml / 300–400 ml |
| Quail | 30–50 ml |
| Adult turkey | 500–800 ml |
| Duck | 500–1,000 ml including spillage |
| Goose | 1,000 ml and more |
Figures are approximate. What matters more is your own flock’s usual intake, which you compare against every day.
What a change tells you
| What you see | What to check |
|---|---|
| Use down 10% or more | Blocked drinkers, low pressure, frozen water; if all works — disease starting |
| Sharp rise | Heat, too much salt in feed, leaking drinker, diarrhea |
| Broilers’ intake stops rising | Slowing growth, disease |
| Day-to-day jumps | Supply interruptions, recording errors |
If water use drops and the drinkers work, inspect the birds and check the feed. Don’t wait for dull hens to appear.
How to measure water
- A meter on the house water line is the most accurate. A simple domestic water meter pays for itself quickly.
- On a small farm, measuring buckets or a marked tank.
- Every day at the same time. Otherwise a shift in reading time looks like a change in intake.
- Separately for each house, not for the whole farm: a shared meter hides a problem in one of them.
Water quality
Cloudy, smelly or warm water lowers intake by itself. Flush drinkers, especially after medicating or adding vitamins to the water: bacteria multiply fast in leftover sweet solution. When treating via water, keep the withdrawal period in mind.
Species differences
Ducks and geese use water for more than drinking, so their norm is hard to pin down. For them, day-to-day comparison matters more (water for ducks). Broiler intake rises every day with weight, so it’s compared with the same day in previous flocks.
The deviation shows on a chart
In EggPulse water use is logged per house every day and plotted next to feed and egg collection. A sudden drop or jump shows from day one, not when the problem is already obvious in the house.
