Here's a side view. We actually did not cut off one end. We used a 90 degree elbow as is. We put a piece of 3" pipe inside the expanded portion to bridge the opening. Then a part of a connector fitting on the outside to pinch it to the wall.

We took your advice and cut half the expanded section that is inside the box.
I wondered about that height after I took that first pic. Hard to tell, but in the 2nd pic, I switched to a different block that wasn't quite as high. Still not sure if it will be too high, but will check it once I get the chickens. Thank you.
I made a couple of the diy feeders and have them I smaller red bricks and they have worked great, I used the inserts that I bought off Amazon. I did make two pvc pipe feeders that are about 3ft long and have the elbows that curve up, not to satisfied with them because my husband added a piece of elbow to the ends to go with what I had on because they were flinging some of the feed so now the gravity element of it does not work right for the feed to come down on it’s own. I wish he wouldn’t”help” me. He doesn’t have any interest in the chickens really.
