Where in the world is this information? This is literally impossible and does not happen. This is the type of information spread throughout the online world more than likely started by animal rights activists knowing that not many people are going to fact check it. You need a different source of information one that's at least plausibleI am sorry to bust through this thread, but this is somewhat wrong. While Leghorns are known for their prolific laying abilities, the Leghorns used in battery facilities (at least many parts of the United States) are injected with hormones to make their body speed up the egg-making process, most of the time forcing the battery hen to lay two or three times a day, ultimately tiring out her body so much and putting a ton of stress on it. Exhaustion from this sped-up laying process is one cause of death to battery hens before the slaughtering time. They also stuff up to five chickens in one cage regularly. Leghorns are already excellent at egg production, but the egg industry is cruel and horrible, not caring for their birds at the slightest.
