Do my math please!I would take the COST/# out of the analysis all together. There is far too much variance in this matter. One year, I paid $26/50# bag of barley, same price for wheat. Last fall, I was able to pick up wheat for less than $13. Same goes for chicken feed. You folks out in the mid west, the grain belt, those who have mills near by can get their feed for a FRACTION of the price that I pay. As far as I know, there is not even a feed mill in my entire state. Also, some folks buy the cheapest feed they can purchase (that would be me) while others pay for organic or other "high end" feeds.
If you want to find out how much your feed is costing you, simply figure out how many days a bag of feed will last you. For example, lets say you have 15 adult birds, and a bag of layer feed lasts 18 days. 50/15/18 = .185# per day per bird. The math would be the same whether you fermented that bag of feed, or fed it dry. Keep track of your feed consumption for a month, or several bags worth. If you want to go even further playing the math game, you can throw the cost/bird/day into the mix, or even figure out how much a dozen eggs cost you to produce. Then, just for grins and giggles, you could figure out the difference in egg cost based on fermented vs. dry, or cheapest layer feed available vs. organic or other high end feed.

I'm just kidding.
