I joke that they are the most expensive organic eggs you can buy. ;)
10 years back, we were getting eggs at something like 25c/egg in feed costs. But we had a bunch of birds that only laid every 2 or 3 days, so they were no where near as efficient as a first year dedicated layer. OTOH, they all had names, we had most of the egg colors, and the bantam eggs were so cute. And the one hen that basically only laid double yolkers.
Also their bedding makes fantastic compost for next year's veggies.
It's a nice system.
Owners of coops know how different are those organic eggs. Totally diffrent color of yolks, also they have totally different smell when they are cooked.
That could be a side-effect from slower winter laying though since we don't use an artificial light.
