If you aren't staying out from the middle of the morning until at least the middle of the afternoon I'd do so. Most of the birds I shoot are taken during that time frame after the hens leave the Toms and then the Toms go looking to breed other hens they might find. I call sparingly and only about once every 15 to 20 minutes and then just watch closely for a bird slipping in without sounding off to even let me know he's in the area.
