Personally, I would definitely scout more. Try and find out where they roost, and where they go after the field.

Pretty soon, unless all 4 of those big boys are satellite or beta males, you can bet they won't be together. Which means if the alpha/dominant male stakes that as his territory, you have now seen your gobbler "flock" reduced by 75% to 1 bird.

That 1 bird may, in 2 weeks, have an appreciable number of hens. Assuming from the manner of your questions that you are relatively new, I don't advise limiting your options to one henned up boss tom if ya' catch my drift...

If possible, get out there before daybreak next weekend and determine where they roost. Go back home, grab a bit of breakfast---maybe a nap---then head back out ~11 am. Determine any strut zones between the roost and the field, any terrain obstacles, and just do some general scouting of the area.

If your experience is quite limited then realize that if you learn nothing else this season, learn the whens, wheres, hows and whys to scouting. It will garner you more birds in the long run than any other aspect of turkey hunting...
