Apart from the obvious moral failure of animal based food, space is an unforgiving environment. You hit on it with the comment about raising ducks on Mars. I can't imagine raising any animals on the confines of ships that humans will use for what could be years long voyages. Plants are the only viable way to sustain a crew for long periods.

i agree, even sci-fi movies show astronauts eating plant-based, hydroponically grown, etc. Just missing the boat (spaceship?) here!
