Thats not what the word humane means. Its not humane to kill a fresh born chick because it won’t lay eggs. You made the chick, deal with it in a real humane way by not immediately killing it.

Also, just personally, I would not want to die by macerator. I didnt find the videos comforting in that way like you did, I wouldnt euthanize a loved one by macerator.
