I have lost seven chickens suddenly. I believe it is due to cocci due to he blood poop. As soon as this symptom started yesterday they began dying really fast. I started corid today. I was wondering if anyone knows how long before chickens get better and how many more should I expect to loose? I have 42 that are about the same age of 4 weeks. I am also treating 17 of the older ones that are about 10 weeks old even though they do not have symptoms. My Easter Eggers seem to be getting hit the hardest. Also what do you keep in your chicken first aid kit? I will always have corid on hand now, but really wish I had it yesterday evening. Any suggestions to prevent future outbreaks as well as what to keep on hand for emergencies would be very much appreciated. Thank you.
