Battery cages, wire-mesh enclosures, are the predominant form of housing for laying hens worldwide (Leenstra, 2016). Cage reduce aggression and cannibalism among hens, but are barren, restrict movement, or the expression of natural behaviours, and increase rates of osteoporosis (Meseret, 2016). In the European Union, as of 2017, 197.6 million laying hens were not in cages, amounting to 49,6% of the total number of laying hens (EU, 2019).
According to ChickenWatch's progress tracker, as of the 28th of November, 2019, 1753 companies worldwide have pledged to remove cages from their egg supply chains.
When will 5,000 companies worldwide pledge to remove cages from their egg supply chains?
This question resolves as the date when will 5,000 companies worldwide have pledged to remove cages from their shell egg and chicken or chicken "ingredients" supply chains within any timeline. Reporting should come from ChickenWatch's progress tracker. If ChickenWatch no longer maintains its progress tracker, another source may be consulted, or the question should be resolved ambiguously.
