Only tape worms and round worms (with heavy load) can be seen in droppings. Tape worms will look like rice pieces, but slightly different then maggots which may have been laid and hatched on the poo after dropping.
I suggest if you DO wish to worm... taking a sample to be tested at the vet ($13-18 here) so they can identify species and load count to make sure you treat the correct parasite instead of treating for what you don't have and accidentally not treating what you do.
The previous poster is correct that only microscopic eggs of most worm species will pass in the droppings of our shooks, with the exceptions I noted.
FOR NOW, before treatment with any medications... the eggs are perfectly safe to eat. Any worm would be inside the intestines and not the eggs. Once you treat
if you need to... there should be withdrawal time for eggs indicated on the label. That is for the medication residual that enters eggs, not worms and I would follow the instructions accordingly.
Also want to note that while pasture/poo management does help keep parasite loads down... getting worms, lice or mites doesn't make someone a bad keeper. They are part of the environment. Allowing them to continually infest would indicate bad keeper. But some of the eggs of parasite worm species are actually laid or present on the exterior of our standard earth worms (which get digested and don't just live in the gut). It's those eggs that hatch in the gut and take foot hold.
To me, testing is cheaper than treating what you don't have.
Good job being vigilant.
