I hunted pheasant for years with out a dog. Try walking zig-zag, not a straight line. It help close the distance if there are not enough people to cover the field. Then, I would go get a dog! Much easier and tons of fun.
zig zag works. Scouting your hunting areas helps too, wouldn't you like to know if there actually are birds where you're hunting?
