Mostly layers here, or should be, but we also have ducks, geese, a turkey, roosters and adolescents sharing water. After seeing worms in poo, it's time to deworm them! We've used Wazine twice before (I think there is a week withdrawl on Wazine), but I think we have the Ivermectin-type that is applied on their backs, as you would for a dog's tick medicine. Any thoughts on the best route to get them feeling better? Egg production is waaaaayyy down and it hasn't been too hot, very few are moulting, so I'm pointing to the worms as the culprit.
