Can a Zooloretto Enclosure Score Money if Filled Via Enclosure w/ Breeding?
It's a good question: the rules state that pairs united by an exchange DO breed; and that you DO NOT collect money for filling an enclosure through an exchange action.  It really comes down to whether exchanging-then-breeding counts as "filling an enclosure through an exchange action", or whether the breeding is really subsequent to and distinct from the exchange action.

My gut reaction was that, sure, it's a bit ambiguous, but why not give the benefit of the doubt, don't be cheap, dish out some money.  Fortunately, I managed to find a passage in the rules that proves my gut is an idiot:


  Exception: NO bonus is awarded when
  all enclosure spaces are filled as a
  result of an exchange. There is also
  NO bonus awarded if an offspring
  produced by the exchange fills the
  last space.


So there you have it!  (Incidentally, I found a useful combined rules pdf online here: http://files.boardgamegeek.com/file/download/48p5z9a045/Zooloretto.pdf?)  You're welcome!
