Life would certainly go on if I didn't know our cost-per-egg. It's important to note egg cost is vastly different than our annual cost-per-chicken, which I don't want to knowLOL I don't really want to know how much it costs us per dozen.. We just bought them a bunch of corn on the cob, water melon, we grew all the kale they will ever want, and I have been buying fish for them too, as little bonus treat. The Egg Thief is already a little salty that they eat better than we do, without actually tracking what it costs.![]()

After all, rooster AGC's glucosamine costs around $50 annually, and he's never laid an egg.
But besides satisfying my curiosity and providing a neat talking point, knowing cost-per-egg has been great for reviewing chicken spending at a granular level, which inspired measures to reduce waste, e.g., buying pans to keep spilled feed edible longer.
As I type this, I'm realizing it would be good to track eggs next year again to review the effect of layer age and a few more years of keeping experience. I prorate housing costs over 10 years and less durable items like feeders/waterers/fans/heaters over 3 years, so it's easier to isolate variable annual costs of feed, supplements, vet care, yada yada. Anywho.
