  • A. To increase the egg's calcium content
  • B. To prevent the embryo from adhering to membranes
  • C. To make the yolk produce more albumen
  • D. To shorten the genetic generation interval

Turning prevents the developing embryo and extra-embryonic membranes from adhering to the shell membranes and supports normal development. Turning does not alter the egg's nutrient content or the flock's generation interval.
