If 10 high-producing Leghorns experience one double-lay day monthly, what is the approximate total extra eggs added annually?
Answer
120 extra eggs.
Even though a double-lay day is an anomaly for an individual bird, when scaled across a flock, these rare events contribute substantially to the overall yield. If ten Leghorns each experience one extra egg per month, this results in 10 extra eggs per month across the group. Over the course of a full year (12 months), this specific incidence of rare performance results in an addition of 120 extra eggs (10 birds * 1 extra egg/month * 12 months) to the group's cumulative tally, demonstrating the cumulative effect of unusual high-output days.
