Chapter 12 - Water Temperature

Drinking water temperatures should be between 50°F to 60°F (10°C to 15°C) for the most comfortable consumption by mature birds, but some studies have indicated that water temperatures of about 77°F (25°C) reduce mortality in chicks and poults. Temperatures over 86°F (30°C) will reduce consumption and birds will refuse to drink if water temperatures are over 111°F (44°C).
