Water: How Much, and Hot-Weather Support
By The Coop Team · Updated July 3, 2026
Quick answer
Water is essential for chickens, with a laying hen consuming about 500 ml daily at 70 F, increasing to 1000 ml above 90 F. Ensure daily refills, regular cleaning, shade placement, and prevent dehydration during both summer and winter months.
Key facts
- Daily water consumption at 70 F
- 500 ml
- Daily water consumption above 90 F
- 1000 ml
- Electrolyte mix per quart
- 1 tsp sugar, 1/4 tsp salt, 1/4 tsp baking soda
- Maximum time for electrolyte water out
- 8 hours
- Apple cider vinegar per gallon
- 1 tbsp
Importance of Water
Water is the number one nutrient, and the fastest way to crash a flock is to run out. A laying hen drinks roughly 500 ml (2 cups) per day at 70 F and doubles that amount above 90 F.
Water Management Rules
- Refill daily.
- Scrub the waterer weekly.
- Keep it in the shade in summer and off the ground so bedding does not fall in.
In freezing weather, use a heated base or swap out ice twice a day. Dehydration in winter is a real killer that most owners miss.
Electrolytes and Additives
Add poultry electrolytes (or a homemade mix of 1 tsp sugar, 1/4 tsp salt, 1/4 tsp baking soda per quart) during a heat wave, right after transport, or when a bird is recovering from illness. Never leave electrolyte water out longer than 8 hours, as it grows bacteria.
Hot-Weather Support
Frozen water bottles or a shallow pan of cool water for the flock to stand in helps on 95 F+ days. Apple cider vinegar (1 tbsp per gallon) once a week in a plastic waterer is a common flock-wellness trick. Skip it in galvanized metal, as it leaches zinc.
