I would experiment, try a hugel bed with some and see if the plants planted on top get affected. I think the juglone is in the roots, so using the trunks might not have much effect, but I am not certain. Some might make good firewood for your RMH
Lots of animals love black walnuts, that's true. The problem is that black walnut trees exude a toxin (juglone) from their roots and leaves, which leaches into the surrounding soil and inhibits many species of plants from growing there – sometimes for decades after the walnut tree is cut. Juniper isn't so bad. It just chases away insects: good and bad.
