Water consumption was measured on 12 groups of 75 straight run day-old Leghorn-type chicks. For 2 years the consumption was measured on a per day basis for the first week. Control waterers were set up in the floor pens to measure evaporation. Feed consumption averaged 6.9 kg per pen for the week. Average water consumption in liters/1000 chicks/day for the first 7 days was as follows, respectively: 8.5, 8.6, 11.4, 11.9, 13.1, 15.5, 16.4. These values are slightly less than the National Research Council (1977) values and considerably less than other reported values.
