I haven't seen them actually call and shoot ducks yet..
IMO - Duck Dynasty is about the family, not the hunting.
Duck Commander is about the hunting - if I want to watch the Robertson's shoot ducks - I get the Duck Commander DVD.
Duck Dynasty gear supports the network, Duck Commander is separate and goes just to the family. I tend to rather support the family if possible so no Dynasty products.
Dynasty is good TV (ish - it can be funny) but it's not a hunting show.
Best line I remember was one of the wives came in looking for decoys and asked someone why the dekes were all up on the roof?
Response was "There was some discussion about how often satellite imagery gets updated"
Don't know why but always made me crack up - probably the delivery....
