The small white moving 'worms' about the size of cous cous or small rice are TAPEWORMS. They get them from eating insects/beetles. Ivermecin will not kill them, and neither will wazine/piperazine/pyrantel ect. Albendazole and praziquantel kill tapeworms, though are not labeled for laying hens.
Roundworms almost never come out moving, to pass in the feces- they are dead. They will appear are vermicelli noodles....
