There is a supermarket hierarchy when it comes to the quality of meat. Tesco and Asda are the bottom as they prefer to pay the suppliers less and make more profit.
Sainsbury's, Aldi and Lidl have better product at reasonable prices.
Of course the M&S and Waitrose more expensive chickens are nicer but their budget meat is no better than that at Aldi.
What I discovered recently is that Waitrose actually sell 5 grades of chicken.
Tier 1: Organic – The highest standard. Birds are free-roaming, fed an organic diet, and have access to large outdoor pastures.
Tier 2: Free Range – Birds have continuous daytime access to open-air runs and pasture, allowing them to forage naturally.
Tier 3: Free Range (Corn-Fed) – Similar to standard free-range, but these birds are fed a specifically enriched corn-based diet that gives the meat a distinct flavor and yellow hue.
Tier 4: Slower-Reared (Indoor/Barn) – Reared to the Better Chicken Commitment (BCC) standards. They are slower-growing breeds housed in enriched barns with natural light, pecking objects, and more space than standard birds.
Tier 5: Standard Indoor – R reared to the UK's legal housing requirements. Note: Waitrose restricts this tier exclusively to slower-growing breeds that have more space to roam than conventional supermarket standard
What you get at each store will vary. Where we used to live I bought all my organic chicken in Waitrose. Where we live now the local Waitrose only stocks Tiers 3 - 5. I have to drive 16 miles to a Waitrose in a town with a different social demographic profile to get organic chicken.
