The device includes a processing station arranged to subject the egg to the processing; a holder arranged to hold the egg in said predetermined orientation for the processing station to subject the egg to the processing. The holder includes a support, arranged to engage one of said two ends of the egg; and a cylindrical accommodation comprising at least two arms extending from the support in use in the longitudinal direction of the egg to engage the egg at a distance from the support, wherein the arms are flexible and the cylindrical accommodation is curved in correspondence with the circumferential shape of the egg. The arms are arranged to yield and align the egg when the arms move over the egg.
