Crossing the Road
I’ve seen a growing trend of people feeding their chickens meat scraps.
Its not a growing trend, truly. @saysfaa linked a bunch of old recipes from last century, they frequently rely on "meat scraps" (which was then a term of art) in this thread. More modern man briefly adopted one of our numerous dietary fads, which we promptly inflicted upon our chickens, in our ignorance. We are now walking that decision back.
Now the FDA says you can no longer use "meat scraps" (again, its a term of art) in making animal feeds. But you can ABSOLUTELY use "meat" "scraps". You just have to disclose them with modern terms of art that better describes the source. "Porcine blood meal" (pig's blood), "Menhaden Fish meal", "Chicken meal" (yes, you can feed chickens chicken - unlike the "mad cow" example, there are no known prion diseases of chickens), "Crab meal", "insect meal" etc.
What makes them "meal"??? Mostly they are dried to remove water, possibly heat treated, then chopped, poowdered or otherwise homogenized.
