I have the entire flock on corid and I've read lots of great material on how to get it under control. I just wanted to rant about my babies and how stupid cocci is... Most aren't appearing sick but there are 3 that are fluffed up and won't drink water without some encouragement. So I brought them in and made them drink rotating each one making sure they all get some meds. I was up till 5 am with them. I took a little nap and woke up around 6am and one had died. I'm very upset about it! The only good thing is the 2 remaining seem to be doing better. They are drinking often on their own now. I hope no more die from this! As soon as I noticed something was off with the sick ones I did research and got them on meds. I just wasn't quick enough this time for the one this time.
