Thanks so much. When I have read about Runner Ducks online one of the problems they list is that they carry worms. That is where it came from. Evidently the article did not know what it was talking about. It will no longer get below 50 here at night and will be 89 on Thursday during the day and is really getting hot so the little ones since they are now a month old are moving into a sectioned off part of the duck pen where they can see the others but no one can get to them. I know they will be happy outside and my trash man that has had to get rid of 600 puppy pads over the past month will be so excited!!! LOL I will miss them inside. Watching them grow has been so much fun. I am still not 100% sure about boy and girl but the one still has the peep and the other the quieter quack so hoping for at least one girl. Time will tell for sure.I don't know where you heard that but Runners aren't any different than other ducks as far as getting worms. The only difference is they are taller than other domestics lol I have never seen worms in my ducks poop. I have seen roundworms in my chickens though.
I do worm all my birds together becasue they all eat together. It's my chickens that actually need the worming though. If I only had ducks and they were kept like most of us keep them []not in horrid conditions] I'd most likely not worm.
I use a herbal wormer from Molly's Herbals.
