So far only wolves survive if they are 1-2 star and there are enough of them because they will attack the flying rats or drakes if you build any kind of roofed enclosure. but that same roof = doom for boar farms as bats get thru any opening and kill them all.

build smarter for your animals to roam in an area for themselves with enough protection, use the iron bars, stone walls and if youre really desperate then just make use of moats

the bats are a real nuisance and is just tedious and annoying to kill, hopefully theyll provide a way to block specific raids in the future
