Thread: Dead duck today

I found this interesting.

I was driving along and saw a dead duck beside the road which had been run over. As I wanted a bit of duck and some feathers for my predator traps I stopped and picked it up. I have just cut it up the drake and at the back end of the right breast there is a bit of steel shot, clearly the shot has penetrated almost all the way to the breast bone, it would be a size 2 i would guess ? The wound is well healed over and so it has been shot some considerable time ago i would guess. You can clearly see the impact point from the car at the front of the bird so there is no doubt that is what killed it. What interests me is .. I have always been told/read that steel shot rusts/festers inside the bird and it will die a slow death. In this birds case that clearly is not true. Your thoughts please ?
Please do not turn this into a lead v steel debate.
