I count 17 birds in the photo. Assuming 6 hunters as Spring said and a 6 duck per hunter limit, that is less than half of the number of birds legally allowed (not taking into account any sublimits which are in effect some places ie. 6 ducks per day, no more than 4 of which can be Wood ducks or whatever). In any event, it’s not excessive at all and just looks like a heck of a good time!

Nothing the government gives you is free.
