I've done that the first time I played.. Killed many deers and was wondering why I couldn't loot their corpse for meat.You may think you have the quest, but you probably don't. I did this as well, thankfully I only killed 1 deer before realizing my quest log was empty.
Go back to the village and talk to Red again, and you should have the quest this time.
Now, I just kill, confirm they're dead (hey, it twitched, another arrow!), and move on. Same deal with the wolves.
