i lost an entire flock of 15 plus a massive roo all in one night with only a very tiny lil openning in the pen to a weasle. he sliced the throats, drank blood of every one of em. then left the bodies for us to find in the morning
it was pretty sad. the next time, we openned the door to find a fox standing about 10 bodies, growling at us. Mangy as sin, he got shot and buried 3 feet under in the middle of nowhere.
That was a rough year. and the end of that flock.
