They will also access a pop door. They used mine for 2 years and scarecrows, cd's flashing in the wind did not deter them in the least. I started feeding chickens myself but as soon as i open the container they started to show up. Even the cottontails showed up waiting for me to walk off. I gave up since their is no solution.
I do have bantams but I might use this as well as another feeder for them, it won't be as high-tech but it will work for them.
