I see runny droppings, some cecal ones, and what looks like some intestinal shed. Do you have a regular vet who may do a fecal test on some fresh droppings? A lot can depend on what they have been eating, and how much they have been drinking as to what droppings look like. Intestinal shed occuring occasionally is normal, but if there is more blood, I would think about using some Coxoid for coccidiosis. Cecal poops occur every so often in all chickens, and it is runny, shiny, smelly, and sticky. It won't hurt to worm them with Fubenvet for the recommended time on the label. In the US, we use Valbazen and fenbendazole, since we cannot get Flubenvet.
