Well, I don't know too much about Europe outside of Norway. But in Norway there is Bear, Wolverine, Wolf, Lynx, Fox. But I guess only the Fox is a threat to the chickens, the other ones normally does not come that close, but I guess Wolf could get that close. Then we have Mink, and a smaller one that in Norwegian is called Røyskatt, it looks like a Mink, but just a lot smaller. They would be a threat to small chickens, but not a hen. But, they love a good meal of eggs. Then it is also hawks, and eagle too. I am from northern part of Norway, and does not know all about southern part of the country.
