Multi stage sampling procedure was applied for the study, hence three rural weredas, nine kebeles and 385 respondents were selected by purposive, stratified purposive and purposive random sampli ng techniques, respectively. Pretested questionnaire was employed to generate data. Household characteristics w ere analyzed using descriptive statistics and Kruskal Wall’s of SPSS 16 was employed to test qualitative variable proportion difference across agroecologies. Performance traits were analyzed by GLM Procedures of SAS 9.2. Tukey test was used to compare means for significant traits. Significant differences were observed among chicken ecotypes in almost all studied performance traits. Lowland chicken ecotypes earlier to mature sexually, slaughter and onset egg laying in comparison to the other two ecotypes but yielded lower hatchability and egg yield. The overall mean age of sexual maturity of local chicken was 7.19±0.04 and 5.71±0.03 month for female and male respectively.
