wow, thanks abunch for the great responses. i didnt quote everyone but im going to sum it up real quick:

Where i hunt there are mainly wood ducks, a handful of mallards and hooded mergansers. So the ducks are used to there being a variety in there.

The woodies are the first to come in and usually decoy somewhatto mallards, but i got 6 woodie decoys i was going to put out early then alittle later in the a.mthrow out 6-8 mallards is seperate little groups

How does this sound?
