This study aimed to estimate the egg production in ten leading egg-producing provinces and overall Turkey for the years between 2018 and 2025 using 1991-2017 data. ARIMA models were used for future estimations in the study. It was determined that the data in the 11 models to be employed in the study be non-stationary, therefore they were to convert to stationary series by one-year differencing. Criteria such as AIC, BIC, SSE, MSE, and MPE were taken into consideration in determining the most suitable ARIMA model in the study. The ARIMA models for the provinces and overall Turkey were identified to be Konya (1,1,3), Afyon (4,1,0), Manisa (2,1,1), Balıkesir (0,1,2), İzmir (0,1,3), Çorum (0,1,0), Bursa (3,1,0), Kayseri (3,1,2), Ankara (5,1,0), Gaziantep (1,1,1), and Turkey (5,1,0). It was estimated based on the data of years between 1991 and 2017 that the share of these ten provinces in egg production of Turkey would rise from 64.84% to 81.01% in the coming eight years. In the ARIMA models employed, a change ranging from + 0.11% to -2.37% was calculated between the estimated value and the real value. Also, according to the average population between 1991 and 2017, the estimated average change in Turkey’s population for years between 2018 and 2025 was found to be +23.84%. It was estimated that given the egg production in the ten provinces and overall Turkey, only two provinces, namely Corum (15.25%) and Balikesir (14.94%), would make less egg production in comparison to the increase in the rate of the population growth in Turkey. Overall, it was determined that the average egg production in the coming eight years in ten province of Turkey would gain 24.94% increase compared to the average production in the last 27 years. Considering these results, it is necessary to conduct studies to inform the consumers so that the annual 203 egg consumption per capita could be increased in the coming years. In addition, these ten leading egg-producing provinces should spend efforts to get a veterinary health certificate or the like to increase Turkey’s share in exporting eggs, or they should at least maintain their current market share and try to get a place in the emerging markets.
