An egg identification system for determining viability of an avian egg is provided. Such a system includes an emitter assembly configured to emit electromagnetic radiation having a predetermined wavelength toward an egg. A detector assembly is spaced-apart from the emitter assembly and configured to detect electromagnetic radiation transmitted through the egg. A light controlling assembly is positioned proximate to the emitter assembly. The light controlling assembly includes an absorbing layer configured to absorb electromagnetic radiation at the predetermined wavelength. The absorbing layer defines an opening through which electromagnetic radiation emitted from the emitter assembly is capable of passing therethrough toward the egg. A processor is configured to process an output signal of the detector assembly to determine viability of the egg. An associated method is also provided.
