Following on from the pheasant season thread. guns are asked to leave hens so that, it is hoped, they will raise wild birds that can be shot the following season.
However is there an argument that after, say, mid-December that if one doesn't shoot hens one should not "cocks only" but "low birds only" on the theory that if the low birds survive we are creating a low bird genetic trait that then gets passed on to next season's birds?
Comments? Certainly I am not the first to make this "link", that we are selectively culling the best birds...the high birds....yet I've never heard of any shoot where this is carried out.
