Hello, I treated my flock with Safe guard goat dewormer as some were getting sick and I suspected it was worms in early November. After worming them, I was able to confirm that they had roundworms. After doing some research I saw that they are impossible to get rid of, however they can be managed so they do not actually cause harm to my flock and get to the point where they start to cause illness. It suggested worming them 2 times a year, once in the fall and spring to keep it to a manageable size. This is what I planned on doing, however today I noticed a few round worms in the droppings that I haven't seen since I wormed them (I check their droppings everyday). It has been extremely cold here lately, but for the last few days we got a warm spell and now it is in the 40s. I read that once the worms start showing up in the poop, it means their overloaded, but how? It has been below freezing here pretty much for the last 2 months, and I just wormed them a little over 3 months ago.They have been extremely healthy, laying a ton of eggs with bright red combs. I am hesitant to worm them because it suggested doing it just every 6 months, but if I'm seeing worms in my poop should I do it now, just 3 months after? Also, it mentioned switching wormers. I really liked how Safeguard turned out, but is there an alternative I can use so the worms don't build resistance? Thanks!
