I did try zoo med but they seem not to like it. As you said if I were to just leave the zoo med in there and wait they probably will eat it after a week or something, and you said they wouldn't starve and I believe you. I just don't feel like going through that process, and zoo med isn't cheap here either.
You and other knowlefgeable people said that they eat dry and will drink. I believe you. I have been feeding wet and mixed with vegetables, and only recently experimented with feeding dry and providing water. Haven't decided yet, but I do respect your experience and know that you know what you're talking about.
