Multiple species in one outdoor bin?

[Cliygh and Mia 2]

If you plan on breeding feeder insects outdoors, I think it should work, as many people breed cultures for their pets. Crickets should work as a decomposer as well, since there's no risk of them damaging the toads. I would also recommend being sure nothing can get in, and nothing can get out, as I would imagine Raccoons would love an easy buffet of earthworms and other invertebrates, and I would imagine accidentally establishing an invasive population of something would cause a harmful change to the ecosystem.

Hope this helps!
