A study was carried at Poultry Research Station, TANUVAS, Madhavaram Milk Colony in Chennai-51 to evaluate the egg quality traits of different native chicken breeds under farm conditions. Because, it is important of consumer preference for better quality eggs. The external egg quality traits like egg weight, length, width, surface area and yolk weight were significantly (p<0.01) higher in Aseel (T₁), Nicobari (T₃), Kadaknath (T₄) than Siruvidai (T₂), chicken egg respectively. The data on specific gravity was significantly (p<0.01) higher in Siruvidai, Aseel, Nicobari than Kadaknath chicken. The internal egg qualities like Albumen height were significantly (p<0.01) higher in Kadaknath, Aseel, Nicobari than Siruvidai chickens. The albumen weight and yolk width were significantly (p<0.01) higher in Aseel than Nicobari, Siruvidai and Kadknath. The Albumen index and yolk colour was significantly (p<0.05) higher in Nicobari, Kadaknath, Aseel than Siruvidai chicken. The yolk height and shell weight were significantly (p<0.01) higher in Aseel, Kadaknath, Nicobari than Siruvidai chicken. The shell thickness was significantly (p<0.01) higher in Nicobari, Aseel, Kadaknath than Siruvidai chicken. The per cent shell was significantly higher (p<0.01) in Kadaknath, Siruvidai, Aseel than Nicobari chicken. There was no significant difference was observed on shape index, Haugh unit, Albumen length, width, per cent albumen, yolk and yolk index of the different breeds. It was concluded that most of the external egg quality traits was better in Aseel than other native chickens and internal egg quality was better in Aseel, Nicobari chicken than Kadaknath and Siruvidai chicken under farm conditions.
