Crowing
Right! It seems horrific, but they have to do something with them. And it isn't cost effective to raise them to butchering age; not when there are Cornish X available that go from incubator to table in less than 2 months.Ducks are no less prone to illness than chickens - and there's no less of need to cull a significant amount of males. If you have too many roosters, you'll have some beat up chickens. If you have too many drakes, they'll kill all your duck hens.
Killing chicks via grinder is quick, and pretty humane - and for hatcheries (and most people growing sustenance levels of meat) its not worth growing out a whole bunch of birds that will take 6-8 months to get to 3lbs - 4 months of which they'll spend crowing, harassing hens, and trying to kill each other. It's much more efficient to grind them up and ship them off to the pet food companies - dogs gotta eat too.
At least by being made into dog food, they aren't being wasted.
