I have been using the typical "no larger than the space between the eyes" rule for determining the size of my feeders and veggies, but how about supers? If measured in terms of width, a very young BD could eat one. If you use the length, it would take a very large BD to eat one. How do you determine this?
No supers can not be feed to babies they must be at least 16 inch +
they have a kink in the digestive system that doesnt straigthen out till adult hood...
they are very difficult to digest
if you plan to feed them to your BD in the future you might want to raise them yourself and if you do that then starting early is best as they take a few months to really get going.
15''+ BUT 16'' is always better than smaller! Your better off with large mealworms, as TREATS I advise even with SUPERWORMS that you do not rely on this as a staple due to digestive difficulties.
