I disagree. I know its more visible but I like the look of the feeding hen. I have a feeding DSD hen and I think it works well. Most of the time, I see hens they are picking at bugs etc and hold their head upright to yelp, then back to the ground. In calf-high grass i find the feeding hen to be very effective at mimicking a lonely hen. I have used an upright hen a number of times and killed birds but I have had a couple of mature toms hang up waiting for the hen to come to them, something about the look of a frozen upright hen that I think they know something is up. Youll kill em with either.
another bonus of a feeding hen, or at least, my DSD, is that it is a little more compact to carry.
