Sexing. As for white poultry, there has been no success as yet in achieving a clear visual distinction between the sexes. A specialized external firm is enlisted to sex these chicks. A Netherlands-based European chick-sexers association (Maatschap Europese Kuikenseksers or MEK) has such specialists on its payroll all across Europe. The difference can be read off in the wing feathers. One specialist can sex 25,000 chicks a day. The male chicks are carried off on a special production belt to the gassing unit.
