I have eight hens possibly affected. Two are particularly very bad. They are lethargic, extremely light weight, and have blood stained loose stool. They are various ages ranging from about 2 months to 6 months. For awhile I thought it was cocci. Now, I'm thinking it is worms. I had been treating them on Sulfadimethoxine for about two days. They've been getting worse. After research, I've realized worms could be the problem. Is it safe to give them wazine after they've been on Sulfadimethoxine?
