Here's my plan for when I process my chickens:
Meat with skin - Freezer (obviously)
Bones and cookable organs - soup/broth
*After being spent in making soup/broth, the bones would then be burnt and the ash put on the fruit trees.
Feet - Dehydrator, then given to the dogs as a treat
Blood - ideally, I would be working over a future garden bed, so just let right into the ground
Feathers, head and other organs not fit to eat - burned and then the ash spread around the fruit trees or in the garden
One of my motivators is finding a use for every piece of the chicken. Even if it just goes to growing future food or given to our dogs. That being said, I welcome any other suggestions on useful things to do with remains.
