I teach second grade and we have been studying insects... The first one that we studied was mealworms. We got about 100 mealworms from a lab and watched the life cycle. Do you think that they will be safe to feed to my chickens? I am worried about the fact that they were bred in a man made environment and that they have been handled (minimally) by 26 germy seven year olds. And the people that send them to us insist that we freeze them when we are done instead of releasing them because they can no longer survive in the wild. (Again, many generations of men involved in the breeding) What do you think? Safe for my girls?
