Hmm, does "British" mean hatched and raised in Britain? £2.11 for an oven ready bird, with the cost of hatching, feeding, bedding, slaughter, preparation, packaging, transporting to a central distribution centre and then to a store - surely a loss leader and if not, how on earth do they do it?
When I was growing up chicken was a luxury item - we sometimes had a chicken joint each rather than a whole bird. The colour, texture and taste was very different, though, and made a memorable meal, not just a vehicle for curry sauce.
