I'm trying to raise mealworms for my chickens (And a little for myself, I want to try eating insects). And I just want to know two things: Do you have to keep the beetles separate from the pupae? And is it okay if some beetles escape into the wild? I ask the latter because two sources told me the opposite answer: one said they are common in the US, and the other said they're not native to North America. A few bugs goes a long way, and I don't want to ruin ecosystems!
