Not real sure whats happening but I will tell you I havethe same issues. Then one day they are gobbling to anything. I think your best friend will be patience for those merriams. It seems sometime that it really doesn't matter what time of the seson you hunt them there is something that might make this happen. Preasure, birds not ready, weather, timing and turkeys just being turkeys. Persistance and patience are key for you.
