I up their protein intake by feeding treats such as Boar's Head low-sodium roast beef, scrambled eggs, non-fat yoghurt, crushed no-salt peanuts, and left over filet mignon chopped small. Our chickens are slightly spoiled, but they are more like pets. I also feed Dumor chick starter with 20% protein. They are over eight years old now, so their molts take longer now and seem to take a toll on their weight. However, they look like show chickens at the end of it!Best and healthy foods/table scraps or anything to give to molting chickens.
