How much water does a chicken drink?
A laying hen drinks roughly twice as much water by weight as the feed she eats. The University of Kentucky puts it at about 0.05–0.08 gallons (6–10 fl oz) per hen per day in cool weather, rising to 0.08–0.16 gallons in hot weather. An egg is about 75% water, and even a few hours without water can knock a hen out of lay.
Hot-weather tips
- Keep waterers in the shade. Hens drink less when water is warm.
- Add a second waterer so a bossy hen can't guard the only one.
- Frozen water bottles dropped into a large waterer keep it cool through the afternoon.
Winter tips
Water freezes fast in a cold coop. Heated bases and heated poultry waterers are safer than improvised heat sources. Check that the cords are rated for outdoor use, and keep them out of reach of pecking beaks.
Gear that helps
- Horizontal poultry nipple waterer (cleaner water)
- Heated waterer base for winter
- Second backup waterer for hot spells

Frequently asked questions
How long can chickens go without water?
Not long. In hot weather, a day without water can be fatal, and even short gaps stop laying. Check water at least once a day.
Do ducks need more water than chickens?
Yes. Ducks drink more and need water deep enough to dip their whole bill and clear their nostrils and eyes.
