Activists will take to London streets dressed as rotten eggs and monster chickens on Saturday October 28 to protest against the sale of Big & Fresh eggs, which come from hens kept in cages for the whole of their adult lives.

The Halloween-themed protest, organised by farm animal protection group The Humane League, will tour several south London supermarkets, including Asda and Morrisons.

Big & Fresh is owned by parent company Noble Foods, which also owns free-range The Happy Egg Co. among several other egg brands. The Humane League is calling on Noble Foods to make a commitment to completely eradicate the use of cages on their farms.

Pru Elliott, The Humane League UK’s head of campaigns, said: “Noble Foods’ caging of hens is a real horror show. The company claims that animal welfare is their number one priority, yet it keeps 4.3 million hens in confinement. For hens, life in a cage is no life worth living. Crammed in with up to 80 other birds, they can barely stretch their wings, and will never experience the light of day.

“This just doesn’t add up, so we’re asking consumers and retailers to boycott Big & Fresh eggs today to encourage Noble Foods to do the right thing and end this practice. The cheerful packaging of Big & Fresh aligns the brand with more premium products and may be more appealing to customers when, in fact, the eggs are from caged hens. ”

The protest is part of a large-scale campaign which has seen activists cage themselves in supermarket trolleys, articles in the press and a Twitter account voiced by Helga the Hen, stuck in a cage on a Noble Foods farm.

The protesters will be dressed as zombie chicks, rotten eggs and skeleton hens, and will set off from Vauxhall tube station at 1pm, moving on to supermarkets in Kennington, Southwark and Old Kent Road.

A petition launched last week by Brighton mum Alex Price, asking Noble Foods to commit to 100% cage-free eggs, has reached over 40,000 signatures.
