A= # of Chickens.
B= Cost of conventional grains.
C= Cost of supplements.
D= Time frame.
E= # of Eggs.
F= Bums
B + C = cost divided by "E".
"D"= consumption period, or whenever when you started your records.
"A" is a factor that comes into play if one would try to reduce purchasing "B' & "C" for chickens whom are no longer providing additional numbers to "E". Those are "F".
Remove those F's from the equation. Roosters are also included in the "F" category.
Other Eggs or no Eggs factors:
B= Cost of conventional grains.

Other Eggs or no Eggs factors:
- Change of season/molt/weather/day light hours will constantly fluctuate your costs.
- Change of diet/brand of feed will have short period effects on egg production.
- Stress & wellness will also effect your bottom line.
) I'm happy if my girls buy their feed over the course of the year. Occasional sale of chicks and pullets helps with the bottom line here. In the winter, I take a loss re: feed costing more than egg sales. Spring and summer turn a profit.
