just because something is pleasing to think, this has no bearing on its relationship to truth.
Like “yeah, I’m sure 🦆🪿 have been crapping out worm 🪱 🥚”?
Earthworms aren’t internal parasites and thus probably never evolved the ability for their eggs to survive 🦆🪿 digestion. They produce 2-5mm cocoons which have the eggs and which are deposited into soil, and which I don’t think would survive duck digestion.
