They're full of calcium, protiem, enzimes, amino acids, etc very great feed (especially if you couldnt free range), that seems to be greatly helping their now winter weather proofed shinyplumage, without otherwise feeding unless snow too deep covering everything. The roaches live on layer and fruit n don't smell or sing. I tried uploading pic a few times but no luck, cause they are bright fruity colors (dubia roaches), and only males have wings/roach look.
If you can upload pic put warning on it I may have night mares. lol Being from Florida originally I can remember those big huge flying roaches give me the willies just thinking about them.
