Thanks guys! It already looked less like a murder scene on their tray this morning. I also noticed it was only really bad in one spot under the perches the other 2 piles looked pretty good. Not sure which one is pooping the most blood but either way it's an improvement from yesterday

I have haven't even made a dent in the bottle of coccivet. I also don't have any other livestock. At least I'll have some left for my new chickens if I have to get rid of the boys.
After they've finished their treatment what foods should I give them to help the recovery?
