My parents dated back to the inter war period and chicken was very definitely a luxury meat to them. My mother was brought up in the countryside but during the war chickens were needed for eggs, so not eaten often. My father grew up in urban poverty and meat full stop was a treat, but chicken was for Christmas dinner.
There are five of us. Left to their own devices, two of the kids alone once ate an entire chicken between them, but under controlled conditions we manage a roast meal (with a lot of sides), a curry or stir fry, stock and possibly some noodles or a sandwich. But we do similar with any roasts.
I have really fond childhood memories of my mother feeding leftover roast meat through the enamel mincer for a pie the next day.
