I'm so sorry for your losses! Just a note of caution....We live in maine and had our first fox loss a couple of weeks ago, unwitnessed, it was only in hindsight that we knew what it was.
A few days later the fox came back and killed 8 of my birds at three o clock in the afternoon! We locked the birds up in the coop for 2 weeks after that. The second day we let them out the fox was back and took a hen from under a bush only 3 feet from our front porch, with my mom sitting in a rocker right there! This attack was also in the afternoon. Since then I've had the flock in an enclosed run during the day (top and buried sides) and locked in the coop at night. We bought a trap and are waiting for bait we ordered online.
just letting you know that once they find you they don't always hunt at night. All of my losses occured in the middle of the day. The darn fox seems to know I have them locked up at night so he only comes during the day.
They are beautiful creatures, but I am so looking forward to using our 22 on him!
Good luck to you, keep us posted!
