This study examined the effect of changes in climatic variables on poultry egg production in Nigeria using past data from 1963 to 2022. The study employed multiple regression analysis and descriptive statistics to meet its objectives. The study found a marginal increase in the trends of relative humidity, rainfall, temperature, and poultry egg production over the years. The regression analysis showed that the R2 value indicated that 72% of the variation in poultry egg production could be explained by changes in relative humidity, rainfall, and temperature. Specifically, relative humidity (-2.91; p < 5%) and temperature (-27.9; p < 1%) had significant negative effects on egg production, while rainfall (1.31; p < 1%) had a significant positive effect. The study recommended that poultry farmers should adopt temperature management strategies, especially during periods of extreme heat, to reduce the adverse impact of high temperatures on egg production.
