It's about $26 for 40 lbs or $0.65/pound which translates to about $0.17 per hen per day. I pay a bit more than that because I ferment my chicken feed with apple cider vinegar and greek yogurt and I add garlic, cayenne pepper, and crushed lump charcoal to their feed to improve their health, the egg quality, and the quality of their manure. Once you have a good culture established you can stop adding the vinegar and the yogurt and just use feed from the previous batch to ferment the new batch. Hopefully I'll be able to grow enough peppers and garlic this year to feed my chickens all of next year and that will cut most of my costs and I can work on making my feed from scratch. Here's a good guide on how to do that.
