That's a tricky one. I went out tonight and tried to listen for some gobbles right before fly up and after fly up and heard only 2. You know how warm it was this evening. Buta few weeks ago I was out one morning when it was probably 40 degrees out and they were going crazy! I probably heard over 100 gobbles in 1/2 hour. If anything, it could delay them flying down for a little while but I don't think it'll turn them completely off where you'll be. They're in the mood for love!
