Chris, thanks for the suggestion. I will compare the nutritional content of barley, millet and spelt. I think fish meal is a good idea except they do get table scraps which regularly consist of fish because my DH likes to go fishing. Looks like two started laying and have nice hard shells with dark yellow/orange yolks the past couple of days so they seem to be getting lots of what they need. I want to keep this up and do what's best for them.
