I have 2 muscovy ducklings, a dozen muscovy eggs in the incubator, 3 call eggs in the incubator and 2 buff geese coming tomorrow, as far as I know, they can all fly, right? My ducks have a fenced day area (because of predators they go into their house at night) but the fence is only 3 ft. high because none of my other ducks fly. Is there a safe way to pinion their wings? Or should I see about finding an aviary vet? I am not sure there is one anywhere near me.
