Near where i live are some large rabbit warrens on B.R. land,it looks good on top but underneath its a mass of wood ,and concrete sleepers, lorry tyres,and old tree roots, which had been pushed into a dissused cutting and grassed over,the rabbits love it here. Every year groups of young lads creep on with there nets and ferrets and try there luck, but they are impossable too ferret, after a long wait they get there kit and clear off, often leaving there ferrets behind.I trap these sets with fenn sixs and check twice a day ,over the years i have caught quite a few lost or abandond ferrets u
