Consider that each egg contains about 12g of protein, 10g of fat, several g of calcium in the shell and so on. All that has to come from somewhere.
Agree. It is perfectly possible to mix your own. But when it comes to amounts and constituents much depends on what is available on your land, on what your local climate is, and on what type of bird you keep. There are smaller thrifty breeds that forage well; there are also commercial hybrids that are bred to eat what's put in front of them in a climate-controlled house and push out 300 eggs a year. If they don't get the nutrition to do that they quickly start drawing on their own bodymass and perish rather quickly, basically lay themselves to death. So as usual: "it depends".
Romania has a temperate to continental climate with cold winters. Bugs only start building up in spring, fruit only falls of the trees in mid-late summer and while I'm sure with the right breed, a good paddock rotation and a low bird density a good bit of their feed need can be met I seriously doubt one can get away with not supplementing their diet, at least from September to May inclusive, with full out feeding in the winter months.
From my own experience I'd say you need at least 20m2 per bird to ensure they don't scratch it bare but that kind of area will not keep them fed and laying under the best of circumstances. I would ask: "What breed? Bantams or large fowl? Define spring. Define autumn. No feeding at all? Or do they get table scraps, access to dung heaps, compost heaps etc.? How well do they lay? How long do they live? Do they reproduce?" There are so many variables. Maybe it works with a few bantams, in your climate, from late spring to early autumn.
Take Ludi's advice and start small. Altsteirer are a good breed for this sort of set-up. They seem to be more self-reliant than most.
