Waterfowl Possession Limits

Can you clear up the possession limits for ducks? I know that the rules say that it's two times the daily bag limit, but does that "possession" still stand once the birds are cleaned and in the freezer? Say for example, once you have killed 4 Wood Ducks, they are in your home in the Refrig / Freezer.....than legally you cannot shoot anymore Woodies???

Am I reading the law too deeply or is it that strict? I've always thought of the possession limit as a situation such as, you are camping and have a cooler with birds in it.....and you cannot possess more than the law states.

Thanks.
