The second programme begins in Senegal where Emmett hears about the aspirational appetite for chicken. She also visits the development kitchen of a global poultry meat company for a taste of the chicken menu of the future, and witnesses the factory-scale kitchens in Northern Ireland, where a workforce of thousands kill and process 200 million birds a year. Emmett questions whether test tube or laboratory reared chicken could ever replace meat from birds.

In Pakistan and India where there is consumer resistance to 'industrial' chicken, Emmett hears from those who hope that smaller scale producers, and the breeds they keep, will survive. She speaks to a UK scientist, at the forefront of building immunity in chickens to diseases that affect them and humans, explains how to vaccinate a chick before it hatches.
