Common average is 1.5 - 2 lbs per bird per week.At 2 lbs x 22 birds = 44 lbs per week / 7 days = 6 .29 lbs per day.
6 pound difference over seven days.Count for spillage ,extra eating etc.
ok I guess that is reasonable math. Although mice could still be helping, maybe?
Admittedly I rarely do anything "math like" except, "chicken math"!
