True,Another persons vermin is another persons sport,just like one of the farms that borders the estate i work on,its a mixed livestock/arable 400acre farm and the land owner has asked me and another person not to cull the rabbits this season so theres enough to breed in the spring
If you had the concent of the landower(s),wich i would for eg i dont see the problem
But if you think, every bit of land has to join onto someone elses land, and rabbits dont keep to boundries and even if you get the next door farmers permission, he still joins onto another farm
