I picked up a small fox today that was hit by a car. I was able to put it in my freezer around 4-5 hours after picking it up and when I went too take a closer look at it (around 8 hours after putting it in the freezer) it had a terrible smell to it. I noticed that it also became very bloated so I decided I should skin it ASAP. When I was skinning it, the belly was very green and had a smell to it but the fur didn't slip. I decided to turn, flesh, and salt it instead of putting it back in the freezer hoping it would give it a better chance. Is there anything else you would advise me to do in order to try to save it?
