But the baby chick macerator drops the fluffy goo into a different bucket. It’s not even necessarily the same processing plant as where the adult chickens are slaughtered for meat. Freshly hatched chicks are sexed so the boys can be immediately culled. Other meat doesn’t go into that macerator, so you’d have to go out of your way to add it to the nugget mix, and the benfit of a few extra lbs of mostly feathers and bone are not going to be worth the effort.
