Distribution of age-at-departure and age-specific removal and mortality rates in the populations of chickens, ducks and Muscovy ducks of the study farms during the 20-month study period. Top: distribution of ages at departure (death or removal). Middle: rate of removal (sale, gift, or home slaughter) as a function of age. Bottom: disease-related death rate as a function of age. Shaded regions in the middle and bottom graphs show the 95% range using imputed values; solid lines show the median. The time series of median, 2.5, and 97.5% quantiles were smoothed using local regression (span factor: 0.5)
