Yes. My husband and I don't eat big piles of meat any more. If I process two at a time, that is all the chicken either of us want to eat in a week. I make soup out of the spent carcass. The skin doesn't really go to waste. I bury the skin with feathers along with the entrails in the garden. People wonder how I grow such lush plants and fruit trees and shrubs. It's because I've been burying the end results of processed chickens for thirty years on the same property. We bury deep enough that when I put an apple tree or raspberry row over the same area in a years time, we don't dig into bones. But the earth is dark, rich, and full of earth worms.
In a true self sustaining fashion, there is plenty of fat in the diet. We grow our own nut trees. I use drippings from bacon to cook with, and there is plenty of good fats in salmon and fish we get from the Puget Sound here. There is plenty of fat in dairy too. Too much fat in the diet with or without chicken skin added to the mix.
I wish I could try that. But my LGD would dig it up and roll in it...
LOL. As I mentioned before, nothing goes to waste here. Carcasses are fed to lgd's. We eat little to no fish here unless it is home grown from ponds since most are questionable. We eat a LOT of beef, lamb, and venison. And a lot of dairy (we milk a variety of A2/A2 animals). We slaughter our lambs in the summer, venison, chickens, and pork in the fall, steers in the winter. Some is preserved by freezing, some by curing in the other room of the root cellar from the cheese and higher humidity veggies, some by dehydrating, and some by canning. We have no waste - bones make broth and soup and/or are fed to lgds, organ meat goes to make and can pâté wrapped in the veil, intestines are used for sausage, etc. Raw hearts are saved and fed to lgd's who are pregnant and nursing for added protein. Everything has a use, even those tiny pieces such as strawberry caps are used - they are fed to the BSF.
Our gardens (for our food as opposed to crops) have the BSF compost and compost from barn bedding turned in each year. Except for the natural gardens that are composted with their own wooded surroundings such as the ramps, etc.
