I use a manual meat grinder to grind up vegetables, and other kitchen scraps for my chickens. If the pieces are too too big, then chickens would not be able to eat them. Result,,,,,,, it is left to night time scavengers,,, So I like to grind things up.
I have an older one similar to pictured, that stays in my chicken area always. After use, I wash up and dry.
I think this may grind up seed as well.

This one is reasonably priced New. You could probably find one in a thrift store , or garage sale for much less.
