Morrisons has revealed rotisserie chickens fly off the shelves at its Cortonwood store.
It sells more there than in any other part of the UK - averaging about 1,500 birds a week.
A Morrisons spokesman said about two dozen of its 470 stores sell on average about 1,000 chickens a week but none come close to Brampton's sizzling statistic.
The store is the nearest large supermarket for many people in Wombwell, Darfield, Brampton, Hemingfield, Hoyland and Elsecar.
Some shoppers told the Chronicle why Barnsley stuffs the opposition when it comes to eating roast chicken.
Lesley Whitehead, 46, of Hunningley Close, Stairfoot, buys two every week.
She said: "There's nothing I like better than chicken salad for my dinner and it's so easy to strip it in one go and make salad. Being a mother, it's so so easy to get it ready."
