The RSPCA is calling on the public to lobby supermarkets to encourage them to sign-up to the Better Chicken Commitment.
This comes after the High Court rejected a legal bid to have standard broiler breeds banned on welfare grounds.
Emily Harris, campaigns manager at the RSPCA, said: “Last week’s ruling shows there is a real disconnect between what the legal system and lawmakers think is acceptable compared to what the public thinks is acceptable when it comes to animal welfare.
“We know that 87% of the public expect supermarkets to ensure that all chicken meat they sell is farmed to higher welfare standards – even higher than the 86% of people who agreed with this back in 2018, showing that this is an issue the public has consistently cared about for many years.”
Marks & Spencer and Waitrose have signed up to the Better Chicken Commitment, but other retailers have not.
The Better Chicken Commitment (BCC) is a set of requirements developed by animal welfare charities asking companies to use slower growing breeds of chicken with lower stocking densities and more enrichment objects.
