As the broilers become older and the area of the house in use is expanded, a minimum of 8 bell drinkers
(40 cm/17 in diameter) must be provided per 1,000 chicks. These should be placed evenly throughout the
house so that no broiler has to travel more than 2 m (6.6 ft) away to gain access to water. As a guide, water
level should be 0.6 cm (0.2 in) below the top of the drinker until approximately 7 to 10 days of age. After 10
days of age there should be 0.6 cm (0.2 in) of water in the base of the drinker.
