I don't understand at all these folks who say killing them is not the right thing to do. As the landowner, you have every right in the world to protect yourself and your livestock. I'm reading here that Granny is not able to catch and haul them off or even catch and then kill them. If she had rats in the basement, she'd use poison and no one would care. The problem I see with poison is that critters that you don't want to kill can get into it; if a cat can reach it, so can you chickens and there enters the risk. Unless.......your chickens are penned up long enough to get rid of the critter and then put up the poison. Go on, flame me, but I don't really care about other folks' animals who they don't take care of. I used to live in a trailer park and a neighbor had cats get into the insulation under his trailer. Animal control brought out traps and then, when the cat was caught, collected $10 from the cat owner and released the cat--all the while charging the other guy rental on the trap. So, he put his pets up for the night and put out a saucer of antifreeze. Good riddance to the cat. I love animals, too, but not to the extent that we save every life etc. My boss even went so far as to have bats removed and relocated from her house! What a waste of money. The no kill shelters around here are always begging the town for more money to keep running--so my taxes are going to pay for something that I really don't want. I'd put all the strays to sleep and be done with it.
