The present disclosure relates to a computer-controlled system for non-invasively identifying the location of the air cell of an egg and determining a preferred extraction point relative to the position of the air cell of the egg, the system having an egg manipulator to hold and orient one or more eggs in a defined position; a candling unit with one or more light sources and one or more detectors; a system configured to run an algorithm for determining the location of the air cell and the preferred extraction point; and a system for positioning the egg relative to an extractor or an egg opener or vice versa from their initial position to the preferred extraction point.

The present invention relates to a method for non-destructively identifying a characteristic of aembryo in ovo, the method comprising: (a) obtaining a sample of material associated with an egg comprising the embryo, and (b) measuring a score value for the presence of, and concentration of at least a first biomarker in the sample indicative of the characteristic of the embryo, and (c) applying a threshold to the score value and concentration obtained in (b) to identify the characteristic for the embryo associated with the presence and concentration of the biomarker, wherein an at least first biomarker comprises an amino compound having a molecular weight in the range of from 140 to 190 g/mole, wherein step (c) further comprises: (i) correlating each relevant biomarker signal with a reference biomarker by matching the spectrum of each correlating signal with the expected spectrum of the correlating reference biomarker using a similarity measure, to define at least one positively correlating signal; (ii) measuring the intensity of each positively correlating signal and scoring its absolute and/or relative signal intensity; and (iii) applying a threshold to the score value obtained from a similarity function to determine the correlated embryo characteristic.

The present invention relates to a hatcher basket for holding newly hatched birds in an incubator. The basket has: &#x2014;a pair of side walls on horizontally opposite sides having a plurality of horizontally-extending openings through them; &#x2014;a horizontally-extending trough which is attached to the exterior of each side wall and which can contain feed for the newly hatched birds; &#x2014;the bottom of each opening in each side wall being located at the same distance above the bottom of the side wall; &#x2014;the top of each trough being located at this same distance above the bottom of its side wall; and &#x2014;the size of each opening being significantly larger than the head of the newly hatched birds but significantly smaller than the thorax of the newly hatched birds.
