Has anyone out there successfully incubated black swan eggs?  I have five eggs already and really can't let them do it themselves since our weather is currently swinging between subzero and low double digits.  This is the first year that I have had them in their breeding season and their former owner never tried to hatch anything due to their (young) age.  I have no broody geese at this time or I'd probably go that route.  HELP
