1 The chart shows an expected range of feed and water consumption at normal environmental temperatures of 21?27?C. As the environmental temperature increases above this range, water consumption may increase up to double the amounts shown.

2 Egg weights after 40 weeks of age assume phase feeding of protein to limit egg size.
