Fwiw, I keep my whitetail (and everything else for that matter) in an ice chest with water and ice for 7-10 days before processing. I do not drain the water unless I need the space for more ice. I have done this for 20 years. I have zero issues of any kind and I prefer my deer meat over everyone else's I have had. People love to talk about how the meat gets all Grey and washed out if you soak it. It does not. The very exterior will but osmosis will make it all uniform and red again after it is removed.
Attached is a picture of some back strap aged as I described, beside some beef we were given. The beef is on the top!
