The size of the eggs is related to survival and chick growth in precocial birds. The interrelationship between egg and chick development can be important for the animal production, supplying data for strategic decisions of economy, handling and animal welfare. This study analyzed the relation between the weight of the eggs and the development of ostrich chicks (N=48) at age of fifteen days old. The chicks were kept in indoor nurseries, in groups, without parental care, and fed commercial feed. It was recorded the weight, the back height and the length of the tarsus-metatarsus. There was a significant difference in the weight of the eggs, but the correspondent body chicken measures were not statistically different. In agreement to the studies in other species of birds, the weight of the egg does not seem to influence the growth of the ostriches at fifteen days old.
