RE: calling, rattling, and scents for secondary rut?
I wouldn't rattle. Rattling won't produce anything I don't believe because most of the bucks have already determined their pecking order by now. You're going to be looking for the buck that just finished breeding 1 doe and looking for the next. I would use doe bleat calls and doe esterous scents.
KEEP IT LEGAL. KEEP IT SAFE. OR WE MAY NOT GET TO KEEP IT AT ALL.
