Dirty water or disease are the primary reasons why poultry do not drink water.
Chickens, it turns out, drink often and will figure it out for themselves when to how, and where to do so. Whenever thirsty, they drink.
When hot and thirsty, they drink.
Under normal circumstances, the average chicken drinks between one and three cups of water each day.
You'll see chickens of all ages dip their beak into the water and tip their head right back, which allows the liquid to drip down their throat.
