Having 1700 acres is a blessing and a curse! A farm I hunt yearly has some days you would swear there are zero turkeys there, the next day 20 birds are hammering. Look to the creeks if they are there, easy place to find tracks and they need water.
They love roosting near steep slopes and ridge points if you have hilly terrain, look for scratching, many times it is easier to find than tracks or scat! Will look like someone had a yard rake in the leaves and left little open spots scattered about.
Get to a vantage point that is high for hearing and open for looking, glass fields with your binos, owl hooters, coyote howler, crow calls are good locators. If they are vocal they will start just after pink lot many times.
