Im glad this came up. I just learned something new about this. My wife is keeping tabs on couple of turkeys she see's every few days. She had to work late the other night and saw them on her way home! whats wierd well it was 8:00 pm!!!! Im home a lot right now because i broke my leg in a skydiving accident a few weeks ago. So Ive been reading a lot of books on turkey hunting. This is what i found on this subject. On full moon nights turkeys will fly down and feed! And it was a full moon the night my wife seen these birds.With turkeys feeding and breeding at night they will naturally clam up. Another possibility is that the population has reached its peek and the breeding in that area has dropped.So birds are not that vocal, but soft calls in there back yards will still work. I got this info from "IN THE TURKEY WOODS", by Jerome B. Robinson. Even though ill have a cast on during turkey season ill still be out there. good luck.
