Good post there sirious and steady bag . Done plenty big warrens over the the last few years and they can be time consuming . But if done correctly you can achieve good bags if the rabbits are there . Some people shy away from big warrens but must admit iv had sum cracking days on massive warrens . Done sum up hexham way were they must be years old and all inter linked nearly 500 plus holes , section by section you can get em moving , but you never get them all no matter how many ferrets .Keep the posts coming
