I've been told that they should be solely on the feed until 12 weeks old, but I can't see how veggies would harm them. I tried Mealworms last week to see how they would react to them, and those little buggers got right to it. They are so instinctive!!! I just want to know if they can eat bits of fruits or veggies yet? Also, what types of worms are best? I'm not too keen on the Meal worms because they are not very nutritious and are Beetle larva, and when it seems like they will eat as many as I give them and look for more. Any input on any of these categories will help, thanks in advance!
