I have lost more than a few lately... all in my FRONT (this is important because there are a heck of alot more in the back yard) yard, all in the thick woodline... 6 on one day, one suffered injuries and didn't make it through the night, and two the next day. I think dog. The neighbor has 60 or so dogs and that night of the 6 gone they were exceptionally excited. They are mostly tied up but 1-3 are either set loose or get loose daily.
Anyways, there were a couple piles of feathers... just like when my dogs get ahold of the chickens (though my dogs never bit bloody or killed one... they just play too hard). To me, that is what a PILE of feathers means... seems to me, the way feathers fall (and after losing a couple bantams to birds of prey) you don't get a nice pile... you get a cluster of scattered feathers in one small 2-3ft area.... dogs, there is a pile like you cut open a pillow and dumped it.
I think in my case the neighbor cleaned up the bodies of the chickens. If I can't PROOVE they did it, then I can't send them a bill. If it was a wild thing that ate them, it wouldn't have all happened in only the front yard. Wildlife would come from my back.... where there was 40 other birds free ranging that were not even slightly hurt and none missing.
Anyways, just sharing.
Oh, I got Dels and Australorps hatching right now! LOL!!! YAY!!! (they are for sale too, btw)
