I was thinking of switching to demands feeders next year but I'm concerned that they will aid in the transmission of d
isease among the deer.
If you hang the feeders high enough varmits can't do much with them. But I did have one where some varmit gnawed a hole in the top of a plastic barrell feeder.
The on in the link is head high. Notice the cameratook a shot just when the feeder timer went off...
