is poisonous, as many other ferns

  It's not poisonous to chickens, plenty of people grow it for chicken feed. I think at this point it's unclear whether it's safe for human consumption. Azolla has a symbiotic relationship with a kind of cyanobacteria that might or might not be safe. Apparently that hasn't stopped some people: https://theazollafoundation.org/azollas-uses/for-food/ https://theazollafoundation.org/azollas-uses/for-food/
