i also have a digital caller and i use the single excited crow, injured crow, some type that sounds like a flock of crows, owl/crow fight, and if that stops working somtimes i'll use some preditor calls. be dressed in full camo make sure you have somthing on your hands too.when i want to get serious i wake up and am out their by sunrise, but most of the time i like to sleep in eat breakfast meet up with a few buddies and go out around 9 or 10am. i like to setup at a feilds edge or in the woods where the trees aren't as tall with lots of open spaces for shots. "crows will fly over the trees so don't setup around big trees where they won't be in range" once in awhile my buddy breaks out the goose blinds and we lay out in the middle of the feilds. for guns i would say bring what ever shotgun you are used to. when i was younger i killed a ton with my 870 28 guage but now i normally use my 11-87 20 guage and sometimes i'll bring out my mossburg 500 12 guage and for shells i like the 6's but if it is windy i might use 4's because the crows seem to fly higher when its windy, this year we bought 6 crow decoys and they really seem to bring them in lower
