Aleta: you raise a question for me... re: your statement about wanting to include animal protein, and using fish. What will a chicken do with a fish that is thrown into the run? do you cook it first? Debone it? At certain times of the year, there are a lot of "junk fish" that can be caught from the lake where my Dad has a camp. I'm wondering how much fish can be fed without worrying about giving the eggs a fishy flavor, or tainting the chickens with mercury and other toxins from a heavy fish diet. Also, can you please explain your statement on keeping the tuna in the freezer for 20 more days. I wish I was in a more temperate zone to be able to raise BSF. I'm also running the idea around in my head about importing some and trying to winter them over in my green house. It's an unheated hoop coop, and I'm in zone 4 or 5A. If I wasn't so squeamish, I'd consider giving some frogs to the girls, but, honestly, I hate it when they catch a frog, b/c I think frogs process a lot of insects!
