“… those on intensive farms are chickens genetically condemned to suffer…”

The chickens reared are genetically selected according to their natural voracity, letting them grow up to 3-4 kg because beyond that would be uneconomical for the whole chain including the environmental impact. The poultry industry actually works tirelessly to ensure that the care of the animal increases its welfare. The more its welfare increases, the better and faster it grows… just as happens to our youngsters who, due to particularly favourable environmental conditions and wide access to food, grow as their grandparents, who grew up in deprivation and hardship, would never have done.
