    The day old chick quality has a great importance for hatcheries and also broiler producers. It is an indicator of hatchery success and assurance of broiler productivity. Chick quality is affected by a number of factors from the time of fertilization to placement time at broiler houses. Generally, these factors are classified as pre-incubation and incibation factors. These factors affects embryo development and chick quality, and in this way post-hatch broiler performance. Day old chick quality is assessed by considering some parameters as colour, vitality, navel quality, yolk uptake, leg confirmation, well formed beak, chick hatching weight, yolk free body weight and chick length. While some of these parameters are qualitative, others are quantitative characteristics of chicks. Because of assessing of qualitative parameters, some scoring systems have been developed to convert these factors into a quantitative score. Fort his reason, visual scoring, Tona or Pasgar score, day old chick weight, yolk free body weight and chick length are used largely for measurement chick quality. In this review, definition of the day old chick quality, effecting factors and also scoring methods are explained.
