I rarely hunt CRP, I personally don't like to tromp through it all day. I usually hunt milo stubble, wheat stubble, pasture draws or tree rows with not really an exception to the time of day. If it's real windy I generally don't hunt but if I do hunt I like to work tree rows or pasture draws. With alot of snow I like to hunt grain fields and tree rows. If it's real cold and snowy/wet I look for the birds huddled up along tree rows or on the sun side of thickets. One of my favorite fields to hunt has it all, a pasture with thick draws and thickets, two tree rows, one big grass/CRP draw and an uncut, no-till milo field that my farmer buddy leaves uncut so he can use it for feed later. We shoot many a rooster and quail out of this quarter section.
