First time chicken owner, flock of 8 birds is about 12 weeks old and we noticed bloody droppings on Friday. Feeling like a bit of a failure, I thought we were doing such a good job 
We started treating with Corid on Saturday in the water. Sunday morning, two of the girls looked all puffy - though still eating, drinking, and moving around - so we decided to go the oral drench route. Dose one was yesterday (Sunday).
My question is, how long until you would expect to see an improvement? Is it normal to continue to see blood in droppings? All I’ve read is that Corid works quickly, just not sure how quickly!
They all seem about the same today. Same two girls are puffing their feathers but they don’t look that dumpy overall. I just know it can go south in a heartbeat
Our plan right now is Corid in the water for 7 days and orally for 3 days.
Also, any tips for disinfecting the run? We use wood chips so I’ve just removed them all
