I have a plan to fence in a run for my 4 girls (due to their garden-destroying and patio-pooping ways), and this area will also be our "orchard". (About 4-5 fruit trees.) What can I plant under the fruit trees (which are yet to be planted) that will be good forage for the chickens, but can stand up to their scratching, and will do well in (eventual) partial shade? I'm thinking perennial. Clover? Also, will the chickens damage the new trees before they can become established? It will be a large area - about 600 sq ft - for only 4 chickens, and possibly a few ducks someday. Suggestions welcome!! Btw, I live in Oregon. Zone 7, I believe. Thanks!
