I third it- a squirrel-so you still have marauding predator. I have NEVER lost fowl in 7 years and I keep havaheart trap set 24/7/365 and HAVE caught coons etc(cats get neutered) and coons get spray painted(to see if they repeat offense,never have) and thoroughly scared by me before I turn them loose. I swear by it and we have only shot 2 coons because they were ill.
