Depends. On Opening Day on public land a bring a single hen, and usually I'll leave it in the vest until 12. I bring it for the PM (CA hunt goes to 4PM) portion of the hunt when the novists are all gone. After that weekend I bring two hens: one upright one feeder. I usually string one or both of them.
On private land I bring at least 2 hens (sometimes 6!) and a jake. I would never dare to bring that many to Public land, maybe 3...but no jake unless I am secluded and desperate on closing weekend.
Due to work, I've had to start hunting in the afternoons and the birds come in real slow and real quiet so I've stopped using decoys and I call alot softer and alot less. Most of my hunting now consists of trying to figure out where they want to roost and getting between them and trying to get their curiosity up just enough to get them in range.
