What you say is correct and it is easy to name certain estates where success is achieved. I assume you are not of my generation when every area had a good stock of Grey's. Throughout the Midlands, Warwk's , Worc's, Leic's etc had them everywhere on mixed farm areas. I hail from Warwickshire and our small local estate could shoot up to 80 brace of wild birds for a couple of days each season. I could shoot personally a brace or two in the 50's on a few acres of marsh adjacent to the Rover factory. A lot of people in East Anglia have ideal conditions, but as you say fostering can work well if you have a good stock, Gerald Gray did this well, I have done it. The major problem now is predators which were kept to a bare minimum when I keepered Grey's. How many shoots (aside from those you name) can afford to have a man full time using bantams and checking hundreds of traps and snares twice a day, not many, therefore we won't ever see the 40's and 50's numbers again. again
