Can you be sure that these were the result of badgers? From what I've read [1], while badgers will scavenge from sheep and lamb carcasses, and eat afterbirths, incidents of badgers killing stock are rare, and more likely to the activity of a troubled/rogue badger rather than the group as a whole, in which case a license for its destruction can be sought.
Fencing to restrict badgers is difficult. We've about a kilometre of fencing around part of our wood to protect newly restored coppice from deer and rabbits. We knew before it was installed that badger routes crossed the proposed line of the fence. The badgers wasted no time in digging under the fence and the rabbit wire to re-establish their routes. We knew this was likely but at least they'd confirm where the routes were. The rabbit wire typically extends about half a metre up the fence from the ground and also goes under the ground a little and then turns so it's horizontal and extends maybe 30cm or so away from the fence.The badgers just dug under the lot. We then installed badger gates where they'd made their path known and made good the holes. The badgers were tempted to use the gates by daily baiting with peanuts. So far so good and this was OK for a few weeks/months/whatever. They then however stopped using the gates and either dug new holes under the gate or to the side. For now, we're still thinking about our next move. For us, the badgers themsleves aren't problematic but the holes will let rabbit move freely back and forth and possbly allow Muntjac through.
