Ferrets don’t realy start proper graft till there second season, saw some that didn’t show any interest at al first season turn into crackers, an saw some that started straight out the nest but I don’t hold much hope till there second season to be fair.
could be either they ain’t dropping down deep enough, the warren too big an needs more ferrets to get the rabbits to panic, or I know a few spots up dales that look amazing, lamp them at night an they are lifting with bunnies, go back to ferret them an you get hardly anything if anything, an the rabbits are in the surrounding smaller
