number of callers

I don't think that you can have too many callers in a group. If one guy can just make clucks well, then that's what he should do. If you have another guy who can do a feeder call, have him do that. If you have a couple guys calling and just making sounds they can make consistently, it's a lot better than having one good goose caller with you. If you have sound coming from more than one area of your spread, it will sound that much better. Let the geese tell you what they want. If they are coming in almost silent, like a lot of the big Honkers do, just make minimal noise. (a feeding grovel works well). If you have a flock of Lessers, Cacklers and Greaters coming in together, they are more apt to make more noise, so call more. Just let the geese tell you what to do. The worst thing you can do is make too much noise if the geese are already committed to your spread. 9 times out of 10 they will flare. Now, if you see the geese working the skirts of your spread and they don't seem like they are going to commit, get everyone calling. At this point, it doesn't matter what sounds are comming from the call, just make noise. If they don't come in, you didn't hurt yourself. I hope that I didn't give you more info than you wanted, but this is the method we use and it works well.
