Last Thursday we lost our family favorite chicken to cocci. On Wednesday she was acting lethargic and I found stools with huge gobs of blood (this was the first sign we noticed and we spend a fair amount of time with them). We treated the whole flock with corrid. The next morning she had past and another chicken was looking really rough. We have force "feed" the second sick chicken the medicated water every few hours since then. She kept looking better then she would start to look rough again after a few hours (she was only isolated the first day since the whole flock was being treated). Today she is finally looking close to back to normal. Her tail is most of the way up and she is running around. Everybody looks normal, although we haven't gotten one egg in two days (not that we would eat them right now anyways). I was doing my farm chores tonight and noticed a poop that had blood in it. It wasn't goobs of dark blood like the chicken who passed, it was a little (although enough to notice it from a distance) and lighter in color. We are on day 3 of treatment and with only 2 days to go I am concerned that I am still seeing blood. Can the corrid cause blood? I am sure you have all seen the post that shows all the different chicken poops and what they mean... well this one looked like the one that said it was shedding it's lining.. So far I have cleaned and bleached out the coop (on Thursday) and we added sand to the floor of our run to help combat moisture (it has been a very hot, humid, wet summer here). By the way they are all a little over a year old.
