When Should Layers Be Replaced?

  • Randy Wiebe is a chicken farmer in Manitoba. Randy has to decide when to replace his layers -- and ideally, he would do it when they are effectively exhausted (still producing, but not as they once were), and when replacing them with new hens will prove economically advantageous (there's the cost of the new hens, the down time, the time it takes for the new girls to ramp up production, etc.).
  • Steve Wilcox has undertaken to find a model that will prove useful to Randy (and others) as they attempt to decide when to change out their current layers.
