I don't know a lot of people do that I guess it sounds like it would take a lot of time. Fermented foods are really good for the digestive systems anyway if I had the right feed I would try it. But mine is to powdery right now. What do you feed?
For protein I think it would be easier to just give chickens some meat scraps or a bit of milk. Making a molt meatloaf seems overly complicated.
What do you think of fermented feed?
