Abstract
A tray (1) with an insert (3) for the support of eggs in an incubation and hatching process has the insert (3) placed loosely near the bottom (9) of the tray (1). The eggs are placed in the tray (1) with the insert (3) and incubated, after which the insert (3) is raised into an upper position or removed from the tray (1). The eggs will hereby roll onto their sides into the position most suitable for hatching. With the invention, the use is avoided of fixed partition walls which occupy space in the bottom (9) during hatching, while at the same time undesired shock effects on the eggs and their transfer to special hatching trays is avoided. According to the invention, only one type of tray is necessary for the transport, incubation and hatching of eggs and the transport of newly-hatched poultry.
