Same deal happened to me a few times. Don't let them suffer and don't waste them. Give them away if possible. One day when frozen up we went pheasant hunting. Shot our 4 birds and was walking back to the truck and my airedale caught 2 more birds on the way back. I wasn't about to throw them in the ditch. I figured we got our limit and Duke got his also. Might have got a fine but not in my eyes. I actually cooked his birds up for him for I raise pheasants anyhow and was no big deal.
