as its shallow digs ,we put a hob polecat in them maybe another later on ,these lads dont mess about if bunny lugs dont bolt its end of story the digs are not more than a foot deep usually as for the jills they cant take the beatings the rabbits give them , they may bolt several but over the day the little jills get too much hammer , if its deep buries we tend to use single ferrets , if it was me mark i would start from the bottom working the hedge up ,you can have too many ferrets in a warren ,get a hob as well ,like i say the jills can come off after several good kickings off the rabbits ,th
