One of my chicks (about 10 weeks old) was having bloody stool. She is the only out of my 4 that wasn't vaccinated from Coccidiosis. I started her (and the rest in case) on Corid powder in their water on Wednesday (so today is the third day) and also gave her a drench yesterday and this morning because I wasn't sure she was drinking any water. She no longer seems to be having bloody poo, though it is runny I think. I'll have to verify tomorrow morning when I look at the poo board. However, her crop is now much larger and softer than the other three. I will leave them without food and water tonight and check in the morning but thought I would ask here until then to see if this is common or if anyone has any ideas or similar experiences. Thanks for any help anyone can give. I'm leaving next Saturday on vacation and I am super worried about her. Edited to add she seems to be eating and drinking fine now and moving around much more than the previous days.
