Good grief, people - the predators are “innocent”, too! They are just doing what they are meant to do...
The OP is in Greece, not an American suburb, things are very different there. He said that rehoming wasn’t an option since people just don’t take good care of their chickens (and I heard the same from a greek friend).
And people on this list slaughter and eat their chickens all the time! Not everyone, and I would not want to eat mine, but surely having chicken as part of your meal is nothing unusual!
Thomas, I applaud you for not wanting to poison any critter. I am so sorry you had to slaughter your whole flock. Hopefully sometime soon you’ll have the means to build a predator proof set up for a new flock!
