The RSPCA is celebrating news that Marks & Spencer has committed to a huge improvement in chicken welfare and is urging other supermarkets and retailers to follow suit.

More meat chickens are reared each year in the UK than any other land animal and a vast majority are kept in conditions which the RSPCA thinks cause substantial suffering.

M&S is the first retailer to pledge to meet welfare requirements for meat chickens across Europe which have been drawn up by a partnership of animal protection groups including the RSPCA.

The groups are urging retailers and food service businesses across Europe to commit to raising welfare standards across their whole supply chain of chicken by 2026.

That means addressing the most pressing welfare concerns in meat chicken production. These include using higher welfare breeds of chickens and providing natural light, enough room, enrichment - such as straw bales and vegetables to peck - and perching in house and humane methods of slaughter.

Sophie Elwes, farm animal welfare specialist, at the RSPCA said: “More meat chickens are produced than any other terrestrial farm animal in the UK, with around 950 million reared each year. Globally, chicken is expected to become the largest meat sector in the world by 2020 as other countries also increase production.

“But despite this rapidly growing demand, there has been little progress made in improving the welfare of the majority of chickens bred for their meat. The scale of suffering within the meat chicken industry is substantial, including the use of fast-growing breeds which can contribute to painful conditions such as severe lameness and heart defects.

“This January it will have been 10 years since chicken welfare was highlighted by celebrity chefs Jamie Oliver and Hugh Fearnley-Whittingstall and sadly there hasn’t been much progress as we hoped there would be.”

She added: “Retailers can often ‘justify’ the selling of chicken reared to lower-welfare standards by citing they are providing both ‘consumer choice’ and a range of price points, which in fact gives little choice to consumers on a budget other than to purchase intensively reared chicken and our polling shows that most shoppers expect all chicken on sale to be high welfare.”

Recent polling shows that 8 out of 10 people (86%) who buy chicken meat expect the supermarkets to ensure that all chicken meat they sell is farmed to high welfare standard.
