Sorry for your loss Dogmother
Be careful now, the fox has tasted the yummy and will hang around for a while.
About three years ago someone dumped a rooster near my house, he couldn't fly the fence and my roosters wouldn't let him anyway, he was roosting on a tree, one day I went out to give him some mixed corn, I found feathers everywhere, then I lost 5 hens, a rooster and 7 chicks to the fox.
I wish If I have culled that rooster, but I thought he will be fine.
