We have added some edging to the carnivorous garden that will double as chicken fencing when the ladies break into the front yard. It wasn't too hard and took less time than expected.
A tench was dug, logs were selected, stuck in the trench, and then we back-filled around them. We occasionally used the chain saw to cut a log down if it seemed to tall for it's spot. Since we had an abundance or logs, we were even able to be a little picky when we selected/placed them, so minimal cutting was required.
You can still see the last bits of the log pile from the really large tree we cut down ages ago. It's really mostly bark at this point. It will get moved to the stick pile or compost pile soon.
