I’ve seen the end results of just that kind of event upon my own chickens, and decimated rabbits. You’re right, it is messy. And there’s a way to call them back so you can eliminate any further issues.
Yes the issue was handled ....
every thing was fine until a 600 ac tract was clear cut down the road last year ...
foxes, owls, raccoon and bigfoots ... over whelmed me ...
I have a few cats, and 1 chicken now.
But I still have about 20 deer that I can whistle in and the squirrels are making a come back now. ...so
things change ...go with the flow
