Hens go broody when you don’t want them to… and won’t go broody when you do. 
Since tapeworms are more rare, I like Valbazen, since it gets most worms with one dose, then repeated in 10 days to get the newly hatched ones from eggs. Tapeworms are usually seen in the droppings as small white specks that move around. Most worms except roundworms and tapes are not visible in the droppings, and may be picked up with a fecal test by a vet.
