I think I might have found a solution

[Dr.GarryTTucker]

i think I have found a no waste solution that works for me. It’s a pvc pipe cut into a u shape with capes on it. I’ve been watching the chickens try to scratch some out but so far so good

Looks like its narrow enough that they cant get their feet in to scratch, Great idea and one I might steal!

That'll do it. I use a piece of vinyl gutter in two cinder blocks, same concept.
