“Animals are sentient beings and we have a moral, societal responsibility to ensure that on-farm conditions for animals reflect this,” EU health commissioner Stella Kyriakides said in a statement.
EU animal welfare standards are among the world's highest, though more than 90% of the EU's farmed rabbits are housed in cages, and in 2019 half of laying hens were kept in cages.
“It feels like one of these moments in history when the tide is turning. The animal advocacy movement succeeded in rattling the cage and planting the seeds of a new era,” said Olga Kikou, head of campaign group Compassion in World Farming EU, and one of the citizens leading the petition.
The European Parliament has also said it supports a ban, and raised concerns about conditions in farming where animals lack the space to stand fully or turn around.
Farmers will be able to receive EU subsidies to help them upgrade to new animal farming systems, the Commission said. EU countries can also apply for money from the bloc's 800 billion euro ($951 billion) Covid-19 recovery fund to help with the transition.
Brussels is also planning a broader update of the EU's laws on animal welfare.
