Even though cocci isn't something we want for out flock but sure beats the alternatives that were mentioned, so thank goodness it can be treated so easily. Hope you see a big turn around and Margaret bounces back as quick as Bob has.It turns out Bob has Coccidiosis i got the Coccivet for him and he is starting to look a lot better already. Now i'm going to give the meds to all my ducks. I might have to sell a few of my ducks. I have too many in a yard which is pretty big but not really big enough for all of them, which might be why they are getting sick. Its just so hard to sell them they are my babies lol but i knew i wouldn't be able to keep all 10 of them. I think Margaret may have the same thing so i will see if the medication works for her.
