1. An apparatus for measuring avian embryo movement, in at least one intact egg comprising:
- egg holder means for holding at least one intact avian egg;
light source means, operably associated with said egg holder means, for directing light into and through each said at least one intact avian egg, said light being of sufficient intensity and duration to stimulate embryo movement, whereby portions of said light exit each said at least one intact avian egg;
light intensity sensor means, operably associated with said egg holder means and said light source means, for sensing instantaneous intensities of said portions of said light exiting each said at least one intact avian egg, and;
determining means, operably associated with said light intensity sensor means, for determining a ratio of range of sensed light intensities to average sensed light intensities, for each said at least one intact avian egg, said ratio being an indication of avian embryo movement.

Abstract
The present invention provides measurement of avian embryo movement in intact eggs by: directing light into and through at least one intact avian egg, with light of sufficient intensity and duration to stimulate embryo movement, whereby portions of the light exit the at least one intact avian egg; sensing instantaneous intensities of the portions of the light exiting each of the eggs, and; determining a ratio of, range of sensed light intensities (IR) to average sensed light intensities (IA), for each of the eggs. The ratio of IR :IA is a measure of avian embryo movement.

11. A process for measuring avian embryo movement in at least one intact egg, comprising:
-
directing light into and through at least one intact avian egg, said light being of sufficient intensity and duration to stimulate embryo movement, whereby portions of said light exit each said at least one intact avian egg; sensing instantaneous intensities of said portions of said light exiting each said at least one intact avian egg, and; determining a ratio of, range of sensed light intensities to average sensed light intensities, for each of said at least one intact avian egg, wherein each said ratio provides a measure of avian embryo movement. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
