I'll take predators over mice/rats...I have the very easy cure for predators but the mice and rats still find their way into the barns, once in a while. I think the cold (extreme cold) kills off lots of 'bugs' that would otherwise affect the birds and people.
Good luck. I'm thinking we should have traveled to Greece this winter. Just might do it next year or the year after.
EDIT: the 'cure' we use for predators is dogs. We rarely have to shoot one. The bear that was taken just a while back was taken legally. My daughter was alone, caring for the farm and our neighbor took the bear LEGALLY, with his Bow.
I prefer april and may in greece. nice weather, still green grass and not too hot.
I don't want dogs near my chickens. a few weeks ago I lost my most beautiful hen due to dog attack. 100% my fault
