hmm I think I'd go with 100 duck sized horses. Not sure I want to fight a horse sized duck, ducks can be mean yo.
Ok mainly it's just because I really want to have a tiny duck sized horse. I'd tame him and name him Howard the Horse (Howard because of the old Howard the Duck movie... get it...nvm) and he would be mine forever [40] )
also I found this kind of cool
and no they didn't look like horses with duck heads. They looked like large delicious dinner.
