dont take this the wrong way mate , but only waiting 10 -15 mins for a ferret thats only been out a few times is in my eyes not long enough , give the ferret time mate , she\he will soon get the hang of moving the bunnys for you . ive ferreted for over 15years and only had i think 3 or 4 digs and that was probably my own fault as i was young at the time and made to much noise , have patience it will be worth it in the long run
