Can Chickens Drink Ice Water? Cold Water, Ice Cubes and Frozen Founts

Cold water, ice cubes and ice lids are three questions

“Ice water” means different things in July and in January. In summer it is a question of ice cubes in the waterer. In winter it is a question of water that is close to freezing, or already frozen. The sources answer each part separately.

Is cold water safe?

Yes. The one text that names a comfortable drinking temperature, from the University of Kentucky's Poultry Production Manual, puts it at 50 to 60 °F for mature birds. That is cool water. The upper limits are the ones Kentucky warns about: over 86 °F birds drink less, and over 111 °F they refuse to drink. No source read for this page names a lower limit for liquid water.

Claims that cold water chills a hen or stops her laying could not be traced to an extension publication, so they are not repeated here. The opposite question, whether lukewarm water helps in winter, has its own page: is warm water good for chickens in winter.

Ice cubes in summer: the sources split

In hot weather the sources agree on the aim. The University of Georgia's Poultry Drinking Water Primer states that cool water has generally helped birds in hot weather and that any water temperature below the bird's body temperature will be beneficial. Mississippi State University Extension's poultry specialist Jessica Wells says that water cooler than the air helps lower their body temperature.

On ice they part ways. Dr. Craig Coufal of Texas A&M AgriLife Extension said in 2017 that putting ice in the birds' drinking water to lower its temperature can encourage water consumption. Mississippi State University Extension's advice on keeping chickens cool says “Do not add ice”, and gives no reason. The same Mississippi State advice calls cut-up fruit and vegetables frozen in water-filled ice trays an acceptable treat, and asks for cool, not icy, water when cooling an overheating hen.

What both sides ask for is simpler than ice:

• Fresh, cool water daily, changed during the day if it warms up (Mississippi State).
• Waterers, lines and hoses out of direct sun. Texas A&M warns that water in sun-exposed drinkers with little flow can reach very high temperatures in a short time.
• Plenty of it. Water consumption can double and even triple during heat stress (University of Georgia).

Ice in winter: a frozen fount is an empty fount

In winter, ice is the problem, not the remedy. The University of Maryland Extension states that birds still need water to survive, that they cannot break through the ice, and that frozen water is therefore not available to them. Ohio State University Extension advises checking for frozen water in the evening.

The ways to keep the waterer liquid, with and without power, are sorted by daily effort in how to keep chicken water from freezing. Snow is no substitute either: see can chickens eat snow instead of drinking water.

A heated waterer keeps the water from freezing; it does not serve warm water. The Farm Innovators instruction sheet for the HPF-100 states that the unit is thermostatically controlled to operate only when temperatures fall below 35 °F. The water stays cold and liquid, which is what the sources ask for. The device types are explained on the heated chicken waterer overview, and complete units are compared under best heated chicken waterers.

In short

Cold water is fine; frozen water is no water. Ice cubes in summer are optional and disputed, while shade and frequent refills are not. In winter, check for an ice lid rather than for the water level.
