I think so, BUT I may be deluding myself. They will pick up things like pop can pull tabs but they drop them without trying to eat them. What we did is set barrels in the woods and places the chickens run. we bought us each one of those long sticks with a clamp on the end they advertise for old people. We use those and five gallon buckets and walk the woods pick junk and dump in the barrels.. We will be doing this for the next 300 years.
