This study was conducted to examine the effect of 4 different quality criteria (chick weight, toe length, shank length and chick length) on live weight, feed consumption, feed conversion ratio and mortality in broiler chicks at the end of the fattening period. A total of 192 male broiler chicks were used in the experiment, and two separate groups were formed for each quality criterion. In 1 day-old chicks, a heavy group and a light group (≥47.7 g and
