Much like in the case of meat, it wasn’t the hens’ fault for the disappearance of eggs off shelves. Instead, as consumers kept buying eggs, stores were unable to keep up with the demand due to strict federal guidelines relating to egg labeling and packaging.
Luckily, seeing the risks involved of entering a nation-wide craze from the lack of eggs, the FDA relaxed those guidelines.
As eggs were no longer sold to schools and restaurants, supermarkets were able to stock shelves once more. So while we did have enough eggs laying around, the real issue was that normal consumers couldn’t buy them.
