Roost is an egg-scanning device that inspects fertilized chicken eggs for their gender. Created for egg hatcheries, Roost is geared to address the controversial issue of chick culling, an industry practice where male chicks are euthanized via grinder, asphyxiation, or electrocution because they cannot lay eggs and are redundant to the industry. Roost offers a more ethical solution with in-ovo sexing abilities to isolate male eggs before they hatch. Specifically with advancements in laser spectroscopy and the use of a carefully calibrated nitrogen laser, an egg's electron activity can be stimulated to determine its gender. This enables eggs to be isolated for more utilitarian purposes, such as influenza vaccinations, food, shampoo, and much more.
To accommodate for different hatchery layouts, Roost is designed with 7-axis rotation capabilities. This allows the device to be placed either in front of loading platforms or over conveyor belt set ups. One arm of Roost houses laser spectroscopy scanners while the other arm has selective clamping mechanisms that isolate eggs scanned to be male.

Roost won a Silver Award at the International Design Awards as well as an Honorable Mention at the European Product Design Awards.
A 70% scale presentation prototype was prepared to demonstrate the motorized functions.
