Earlier quoted context omitted.
Are these crushed chicks also processed and sold (for example, as animal / pet feed)? If not, (I am wondering) why can't you just release them in the wild - in some park or forest and let nature take care of it - it's less cruel (in my opinion) if the chick becomes food for some other wildlife.
How on earth is that less cruel? Have you seen how birds eat each other?
Moral justification - it becomes food for someone else thereby giving them life.
