Our chicks/pullets are 11 weeks old. About 4 weeks ago, we had one unexpectedly die. (just woke up in the morning and one was dead) Found some blood in some droppings and immediately started the other 8 on Corid. They almost all had developed some blood that day. They all did great. I treated full strength for one week and then prevention strength for another week.
Also, their poops completely changed into what I would think as "normal bird poop." I know there is a huge variety and I have looked at those gross charts. However, these are our first chickens. Before I knew they were sick they all had kind of runny, sticky, smelly, light brown poops mostly. (like a cecal poop but it was the majority of their poops) After treatment, it was much more normal.
Anyway, they are off meds for 2 weeks and they are no longer on medicated starter. I went out today and noticed a bunch of that icky stuff from before I knew they were sick. They are acting normally but I'm worried they are getting sick again. I don't see any blood but I didn't see any last time until one was dead.
What would you do?
