I always try to kill a bunch of hogs and leave them laying over three particular two week periods. My neighbor had a horse die, he has a small place, so I took it as it coincided with one of the times that I need my coyotes with a full belly.
From my antlerless hunting and taking the time to measure the fetus within, I've got a very good grip as to when I have fresh fawns on the ground after collecting a decade and a half worth of data,
I also don't do any shredding until the first of August. The deer need the cover, and I don't want to hit a fawn as I've done that in the past. Actually, I cut everything I won't do it again until the same time next year. I shred only once a year, starting in August, because of a number of lessons learned. Deer are very reluctant to leave my place on the boundary fence line, and I think it is because all my neighbors mow their property immediately before hunting season and their boundaries look like they are a concrete road. I see deer come up to the fence and look across and disappear back into my place all the time.
