When I slaughter my chickens, practically I try to use every single bit of it to make good use of it. Here is a list of what I do with my chickens. 1. Feathers-they are sent to my friends wife, she grinds them up, mixes them with cow manure and other goodies to make planting pots. She gives my wife a few to plant her herbs. 2. Chicken blood-My favorite! STINK BAIT! I use the chicken blood with a special homemade concoction and make some real nice stink bait for catfishing. I give a few tubs to friends, they swear by this bait. 3. Guts-Goes to the compost 4. Chicken Feet-I use it for dimsum. I also boil it with the bones to make a richer broth. 5. Bones-Use to make broth, after I make the broth, I grind up the bone to make bone meal and feed it to the dogs. 6. Head and comb-goes to make broth too, comb is real good eating too! I don't like to call my birds dual-purpose, but "multi-purpose."
