It's a recent experiment, we were on the more reasonably priced organic feed until I discovered my local feed store had this stuff over the holidays, so we're trying it out. The quality of the eggs is absolutely miles above what I already considered really good eggs though.
I'll probably get around to making our own someday, but I'm not there just yet.
I've seen someone just chuck a load of split peas in a plastic barrel and submerge with rain water. It naturally ferments with occasional agitation and this is supposed to be good for the chickens. So not so hard to do when you get to that point of wanting to try it.
I mean if you add everything up - land value, labour, food costs, etc - I'm fairly sure they're selling eggs at a net loss, however, it's not a capitalist endeavour unlike the industrial production. And IMO that is the key difference, that is, they produce for themselves and sell the excess and earn some money off of it, it's not their primary goal to do so.
Or they're using "surplus" resources (like their backyard, and domestic food scraps) that they'd still have otherwise. Which is something that is not commercially scalable. Unless, I guess, someone tries "Uber but for chickens".
OTOH for shop bought eggs you also have to add transport (fuel/truck maintenance), storage, commercial land rent/interest costs, electricity, and of course the mark-ups along the way by processors, distributors, and—most of all—the shops themselves, that use their monopoly powers to reduce the margins for everyone else. And if we're doing like-for-like, you have to buy certified 'Pasture Raised' eggs.
Exactly, even with it being excess, I think the motivation is to reduce waste versus produce money in these situations. They have uses for the waste, it can be eaten by an animal, but that’s also true if it doesn’t get sold
