Greetings, and Happy Fourth! My flock has been having pale-ish combs for a while now and I found some round worms in some poop. I went to the co-op and (after much research here) got some Wazine, which I treated them with a week ago. Today, I noticed another tiny round worm in more poop. Since it's been a week, shouldn't there be no more worms? My plan was to treat with ivermectin in another week, but now I am afraid to treat with it because of what I have read about the broad spectrum wormer creating an overload of dead worms and causing the chickens to get sick and/or die. Do you have any recommendations? Should I treat again with Wazine? Do I need to wait another week? Would it hurt to treat with Wazine now and wait two more weeks for the ivermectin? Also, how long after successful treatment should color return to their combs? Thanks for your help!!!! Melanie Momma to three kids, 4 dogs, and 31 feather babies.
