Non-invasive and cost-efficient

CHEGGY and CHEGGY Zoom in practice

The animal welfare-friendly alternative to the practice of culling day-old male chicks is in ovo sex determination with CHEGGY and CHEGGY Zoom. This fully automated machine uses hyperspectral imaging technology that identifies the gender in the brown layer lines by embryonic plumage colours. It is known from experiments and test series that the quills are already visible around hatching day 10 and that the gender-specific colour expression in brown laying hybrids already differs significantly on day 11. In the CHEGGY Zoom, the technology has been further developed and even more information can be obtained from the individual egg through the use of line scan cameras, improved light management and special algorithms. The CHEGGY Zoom is therefore used in compliance with the law and under the conditions of the KAT.

CHEGGY / CHEGGY Zoom is able to safely check up to 25,000 eggs per hour. Thanks to its non-invasive process, there is no risk of contamination and no risk of injuries to the embryo.
