The parasite is coccidiosis. It is from wild birds feces. It causes a liver infection which is when I would see symptoms. All my birds have it. The vet at ISU recommended two wormers, I am not sure it is a wormer, it is given the same way as a wormer though. One ounce to 2 gallons of water for 7 days. My local vet got the birds on something based on ISU's recomendations.
It took the smaller birds, only one rooster. I lost 2 at about 6 weeks then thought it was over, then lost 4 at 9 and 10 weeks before I went to ISU. If you want to create some theory no smokeys were taken, even though some are small.
I've done all I can, and I think it will clear. I still feel OK with the birds I have. I feel like this took those small ones that I would want to keep only because of their color. The best ones are still there.
