I have a small flock of Iowa Blues, one roo & 5 hens. A fecal sample taken to my vet showed multiple parasites, including coccidia. I bought Corid & have Ivomec pour-on 5mg/ml. Doing lots of reading, I've learned about Valbazen, & would like to know if: 1) can I use the Ivomec which I already have, or is Valbazen better? And 2) which would I treat first, the coccidia or other parasites? My vet has sent the fecal sample to a nearby state lab & as yet, I don't have all the results. I'd like to get them started on something, but perhaps I just need to be patient. At the very least, I'd like to be prepared. Any help would be appreciated! TYIA!
