If you are shooting for a pest control purpose, the land owner has granted you permission to remove the problem. Not to pick and choose what you shoot at. By the sounds of your shoot, there is a very clear reason they want the rabbit population removed and I would have no hesitation in shooting young and old alike.

Other shoots may be different where the land owner just wants the numbers controlling. And this is where the fine line comes in. Do you shoot the young as well, running the risk of removing all the population and drying up your shoot. Or leave them and run the risk of losing your shoot through not being effective. Tricky one eh?

My shoots are clear and consice from the landowner, remove them all. And because I have been effective on some of his fields (he has land all over the place), i have been granted permission on other areas and with other landowners. Word gets around if you do the job well.
