Both !!! Lol ,
The submissive hen is for the most part most effective in conjunction with a jake or gobbler decoy, that's where it will be most effective - place one at the feet of said decoy and gobblers go ballistic
if you hunt in the edges of fields , or terrain where there is little ground cover where turkeys can readily see a hen squatting on the the ground from a good ways this may work well for you
If you ever watch hens or a flock of hens in the spring for long periods during the day you will notice they spend much of their time feeding , a feeding hen decoy looks very natural and authentic like everything is a-okay over here
