Sounds like ya got a hen problem.Just to dang many.Later in the day when the hens move off to nest the gobblers will be more cooperative.Somethin to try is move in as close as you can while they are still on the roost.Try to seperate the gobblers from the hens,then set up and call.Spookin a bird off the roost isn' t always a bad thing.It can sometimes work to your advantage.Good Luck
