This has been covered, but here we go. Are you going to get it mounted? If yes, then get it to your taxidermist. The longer it sits in you freezer, the more likely it won't end up on your wall. It's not like you have to fork over a ton of money for a deposit, and it's unlikely that he'll have it completed for you in a real short time, so you'll have time to drum up the few bucks needed to pay for the mount.
If you are going to have it in your freezer for a while, then at least put it in a couple freezer bags. Wrap wet paper-towel around the feet to keep them from drying out. I like to freeze it on the rack, then use a vacuum sealer and wrap it with that. The reason I would freeze it first, is you'll draw the blood out of the specimen if you vac it while it's soft. This also applies to the thawing process as well, if you were to leave it under vac while thawing, it will also draw the blood out of the shot holes.
Your bird is still fine, and will probably be fine for a couple months (or longer) if left unwrapped, but why take the risk? If you really want to get it mounted, then get it to the guy who's actually going to take care of it. The other thing nice about getting it out of your freezer is, that once it's at the taxidermist, it doesn't count against your possession limit.
