The screen is about 12 to 14 inches off the ground and yeah the turkeys will get right up in the feeder, also they will pick the fine stuff off the ground that falls thru. The pipe is connected to a toilet stool flange that sticks thru the bottom of the can, the bottom of the pipe is about 1" above the screen in the trough, be sure and anchor the bottom part of the pipe, I did by running a 2X2 across the middle of the trough and putting a screw thru the inside of the pipe into the 2X2. I also anchored the can down to the braces on top of the feeder by using 4 screws into the 2X4's it sits on. It holds about 200 lb of corn and in the busy seasson it will last about 10 days. I don't know about the rubber trash can though, the squirrels may eat it up. I have 4-2X4's for the can to set on across the top, there are 2 right next to the pipe, one on both sides and close to the pipe, and 2 on the edge of the can.
