I've killed most of my birds in the morning, but I love going out around 3:30 or 4:00 in the afternoon and finding a lonely gobbler. If you can find an afternoon bird, he will usually respond well. Two of my birds I killed last year were after 4:00. The other one was only ten minutes after flydown. If I had my choice though, it would be to roost one the night before and get him the next morning.
