I think you have enough upright heads. I would personally go with feeders. This will give you a 1 to 4 ratio roughly and should be pretty good you could even thin this down more in the future.
Thats what I do and it works great. I always set about 6 "walkers" in my spread.Mac Island said:I am going to disagree with everyone else. Buy six feeders and six lookers. Use the feeders in you "main" spread and then use your six lookers about ten yards downwind of your spread. This gives the impression of a small flock of monster honkers that have just landed and are walking in to feed. The great big lookers look like old, wise birds - there is not a better confidence decoy! This is a super deadly combination.
