Lighting Guide
Commercial Tetra Brown chicks


The beginning of egg production is stimulated by a number of facteurs, most important being the weight and the increased amount of lighting. In the commercial laying chick industry, this knowledge is being used to develop a lighting program which maximizes the amount of laid eggs, their size and global rentability. To optimize the genetic potential of the Tetra Brown laying chick, we should conform to the principals of this basic lighting program.
