I gotta correct here: my big boy does fly and he and his sis like swimming a lot! Just not sure where I should house mine now as they seem to grow tired of their current room mates (Rouens) and pick on almost everyone else too. I threatened them to put them in with the geese if they don't stop. Lol. Jk Gonna have to switch things around a bit and maybe put them in with another group. We'll see.
