This study was conducted to determine the effect of fermented concoctions in the laying performance of native chicken. The Randomized Complete Block Design was utilized in the study with 75 native layers in 5 treatments with 5 replications. The treatments were: tA- no supplements, tB-Fish Amino Acids (FAA), tC-Oriental Herbal Nutrients (OHN), tD-Calcium Carbonate (CaCO3) and tE- Cecical Powder, (vitamin-mineral supplements). Results of the study revealed that fermented concoctions supplementation showed significant results in the average egg production and feed conversion ratio of native layer (Darag chickens). LSD test revealed that CaCO3 prepared from chicken eggshell was significant in terms of average egg production and feed conversion ratio (dozen of eggs produced/kilo of feeds consumed). The findings imply that fermented concoctions was effective in the laying performance of native chicken during the 90 days period of the experiment. Calcium carbonate supplementation in the daily water requirements of native layer chickens was significantly enhance egg production.
