Last week I got 4 new chicks and 3 ducklings. Last year I had a chick die from coccidiosis. I'm new to ducklings this year, but it appears one of my ducklings might have coccidiosis, (groggy, stumbling, hardly walking, unable to hold its head up when sleeping, and sleeping with its eyes open). I have sulfadimethoxine, but I'm wondering how much to mix with their water? I'm going to treat all the new chicks and ducks, because they have been in the same bin for playtime a few times a day.
