In case the need ever arises, the doctors at the Clemson Livestock Poultry Health Lab are helpful. Called this morning to see what they thought was wrong and if I should consider a necropsy. Doctor said I'm overcrowding them and its probably coccidiosis from the vaccine. Never expected to get 28 chicks, let alone expect them all to survive to 3 weeks. I figured they were good with about 1 sq ft until I put them in the coop in next week. Also told me that I probably shouldn't have had them vaccinated for Marek's either since I didn't have an existing problem. Now I've turned them all into potential carriers. Starting to wonder if I've done anything right at this point. And sick chick #3 just died in my desk drawer.

She told me to give the Corid 2-3 days to work, and if it doesn't I should bring a live sick bird to them for necropsy. Seems like I'm losing one every 6 hours, at that rate I'll lose half before then. Sorry if I'm being annoying - everyone here thinks I'm taking this too hard. "They're just birds." "You were going to process them eventually anyway."
