I also have a fox problem here. I do have Maremma and two other dogs too watch my chickens.Well, really still no eggs! A random egg every few days, but that's it!
However, I did learn that a friend about ten miles from here lost 8/12 birds! Of the four left, one is a rooster who is missing some tail feathers. Culprit was a fox! Ugh!
Also, learned of a duck just a mile away, snatched by a fox! Ugh!
Lost a hen and my Rooster also lost most tail feathers. That was last summer.
My hens stopped laying for a week.
