The outbreak of Avian Influenza in Nigeria has led to job losses, health problems, reduction in expected income of poultry farmers and a decrease in the demand for poultry products. This study was designed to determine the monetary value of stock lost, identify the determinants of the future employment decisions and the constraints faced by poultry farmers in the Federal Capital Territory of Nigeria. Data for the study was collected from 40 poultry farmers who have suffered losses due to the outbreak of the disease. The total monetary value of the stock lost in the study area as at 2007 was N142, 741, 000. 45% of the respondents have abandoned poultry production while 32.5% have reduced the size of their poultry business. Furthermore, only 22.5% have restarted their poultry business without reducing the quantity of the initial stock before the outbreak of the disease. The determinants of the decision to abandon were; amount of compensation received, educational level of the poultry farmer and total number of stock lost. The factors influencing the decision to reduce the scale of operation were; level of education of the farmer, years of experience in poultry production and the amount of compensation received from government. The post Avian Influenza outbreak constraints faced by the farmers were; inadequate compensation, low patronage by customers and low level of accessibility to agricultural credit institutions.
