After reading the thread about mealworms here on BYC I decided to raise some for my chickens. I bought a carton at our local feed store and put them in a plastic box with oatmeal, bran and a couple of slices of potato. They seem to be doing fine, but I just read a post on the mealworm thread that the giant ones are sterile. I checked the carton mine came in and they are giants! Has anyone had experience with the giants? If they are sterile I may as well feed them to the chickens and start over.
