This utility model provides an egg candling machine, belonging to the field of egg candling machines. It consists of a base plate, an egg candling mechanism, a lifting and flipping mechanism, a support plate, and a clamping mechanism. In this solution, the output end of the forward and reverse motor drives the gears to rotate. Since the two gears mesh with each other, they rotate simultaneously. The rotation of the gears drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the support plate to flip, so that the egg, which was originally supported by the support plate, is now supported by the egg tray. The egg flips into the egg tray, and the egg tray covers the support plate, allowing the egg tray to cover the egg. The retraction of the electric telescopic rod B can drive the support frame to move on the sliding rod B. After the support frame moves, it presses down on the egg tray, so that the egg tray and the support plate are tightly fitted, ensuring that the egg tray will not move after the support plate flips. After the support plate flips, the egg enters the egg tray. The extension of the electric telescopic rod B drives the support frame to move, and the movement of the support frame drives the egg tray to move, so that the egg tray separates from the support plate, allowing the egg tray to be directly removed.

Disclosed is a method of determining in-ovo gender and / or fertilisation status from an egg. The method comprises optically exciting the egg with light from a laser source; measuring autofluorescence of the egg over a period of time; calculating a fluorescence lifetime indicative of a decay of the autofluorescence over the period of time; and determining the in-ovo gender and / or fertilisation status based on the fluorescence lifetime. The fluorescence lifetime is an intrinsic property of the egg and indicative of the gender and / or fertilisation status of the egg. As such, determining the in-ovo gender and / or fertilisation status based on the fluorescence lifetime provides an accurate and non-invasive method for determining the in-ovo gender and / or fertilisation status.
