Egg production fell because of avian flu, which the US has regulatory restrictions limiting the usage of the vaccine in agriculture compared to other developed nations. Its not an intentional crisis.
Egg prices raised because the government asked for the killing of a hundred million of chickens - for fear of spreading bird flu. It may have been the right call, we’ll never know.
Small difference, but important.
Here, CNN is obscuring the fact that the chickens killed were not tested or confirmed to have flu, but some around them might have so they had to go too.
