I took down my old "Little Giant" because they were finnicky and spilling food everywhere. I made one of those brute trash cans with the PVC elbows going in it. While I don't stand out there all day, I've never seen them eat from it. I even go in and take food, let them eat out of my hand, then I toss some into the elbow. I'm wondering if the inside of the PVC elbow is too dark and they can't see into it. It's inside the coop and while there is a window, I'm not sure how long I should give it.
