So you dont know of or have never heard of a single shooting estate where the boss makes his keepers leave the foxes for the hunt? I know of a few, and its pretty simple really, they just have to release more birds to account for the extra losses due to their lack of predator control.
Admittedly, very few wild birds shoots will make money, but i never said they would, most are privately owned shoots, not commercial shoots.
Have you ever been down to Norfolk where there is alot of large wild bird shoots that are shooting alot of game?
Some people are more interested in shooting real wild gam
