The following research was conducted  with a major chicken producer in the United States. The tests were conducted using four chicken houses over a seven week grow-out cycle. Each chicken house was split into two groups - 1. the Control Group; and 2. the Test Group using the Hexahedron 999 Biophoton Structured Water together with Trace Minerals. The Control Group in each of the four chicken houses had 31,008 chickens - and the Test Group had 30,800 chickens. To account for this slight difference in numbers between the two groups an adjustment factor of 0.99329% has been calculated.
