I would eat them. Think of it like this. If I go out hunting pheasant with a dog, shoot a bird and the dog retrieves it. Now some dogs have real soft mouths, but none of the ones I've ever hunted with. They all gave them a little chewin! You learned a lesson....well maybe your kids learned a lesson. No sense is wasting a meal and ultimately the life of a chicken you cared for over the last 5 months. It may sound weird but respect the life of that chicken and eat it, then it wasn't all for nothing. Also if you do decide to eat it, then maybe you will get another lesson in there.....how to clean and cook a chicken. You'll do no worse than any first time hunter, although maybe the DH already knows how to do this? Enjoy the dinner!
