Does The Deer Breeder pay silver for empty stables on every player's board, or only the owner's, and how often?
The designer confirmed the owner-only rule and that the board's two spaces count as one stable; the treatment of helper-card stables is not settled in the posts.
Only your own stables count, and each empty stable pays 1 silver once per round, after step 3 of the farm phase. The two pig spaces printed on the board count as one stable, so they pay once when both are empty.
