When the hard frost comes i go ferreting . Not for the pot , but to replenish areas . Been doing it for 15 year . Myxi once and rhvd 4/5 times . But the virus blows through quickly now and doesn't seem to wipe 95% out the way it did . It's jmo that the varied blood strains I'm introducing is creating an old mongrel rabbit more capable of fighting back . But as bosun says , they don't seem to branch out . Imo , that's due to the insane amount of predators now . No lapwing nor curlews will attain to that . Be nice if folk would drop a few instead of always necking every one they catch
