How to Use This Calculator

Enter the initial flock size placed at the start of the grow-out or laying cycle.
Enter the current flock size (birds alive today) and days in production since placement.
Review Cumulative Mortality Rate — industry benchmarks are under 4% for broilers and under 6% for layers.
Check Livability percentage (100% minus mortality) to compare against your integrator's standards.
Use Daily Mortality Rate and Projected Weekly Losses to detect early disease or management issues.

What each input means

Initial Flock Size: Total number of birds placed at the start of the flock cycle.
Current Flock Size: Number of birds currently alive in the house.
Days in Production: Number of days since flock placement.
