Meat – Home-made fermented/ cured sausages numbing sensation

Chuck? As in beef chuck? Not that it won't work, but it'll be slightly different taste and texture wise than the more common pork sausage.

I don't think the # of grinds is the issue. I'd be looking more at:

• temperature. Do you put the meat in the freezer for an hour or so before grinding, and are your bowls/grinder/etc cold? If your meat gets too warm, it'll separate from the fat, resulting in a mealy sausage.

• are you beating the ground meat & spices with the paddle blade and a bit of liquid at the end? You want to do that to produce a bind and end up with a tight (not crumbly) sausage.

First, most sausages are made from ground pork, not ground chicken. Second, most chickens that we eat are not killed as chicks but when they are larger. Third, in the vast majority of countries there are rules around cleaning animal carcasses before using them, such as removing at least the bowel contents if not the guts themselves. There are also rules about being humane to the animals. Putting live animals straight into a grinder would violate these rules.

But even if you don't believe in government inspectors, ask yourself - why make a nasty sausage with feathers, bones, and poop in it? Who would buy that a second time? And why waste (assuming by chick you meant a large fullsize chicken) the parts you can sell at a much higher price per pound or kg than you can sell sausages? It makes way more sense to remove the breasts and legs, and use the wings, back, neck etc in your cheaper dishes. Which, as I said in my first point, are probably not sausages because chicken sausages are unusual.

It seems the videos of very tiny chicks (just hatched) going into a grinder are real, but the output of the grinder isn't used for sausage or any other human-consumption. This is done for male chicks in egg-producing operations. The output of the grinder may go to pet food or simply be disposed of. Apparently the grinder is considered more humane than putting a bunch of live chicks in a plastic bag until they suffocate, or some of the other culling options. See Jefromi's Wikipedia link for more.
