Oh, Brian, that is absolutely awful. I am so sorry for your loss. How do they know it was a fox?
Lilwanis, that's terrible that you can't have roosters. How did you find this out? This is going to sound a little crazy (well, crazy to anyone but you guys), but my biggest pause from moving from this house that is waaaaaay too small for our family is that odds are, our next house will be someplace I can't have roosters. And the idea of giving up my roosters is abhorrent. I totally get your devastation.
A neighbor called animal control. I am going to see what I can do in the way of permits, but am not feeling hopeful. Rumor has it that others have roosters in my immediate area, with a permit, I doubt it, but worth looking into. There are eight neighbors surrounding my backyard. I am so sad right now.
