Lost a chick a few weeks ago to what I think was cocci but aren't sure. They were 14-15 wks. old at that time, I saw no signs of blood in poo, just one girl started laying in run, lethargic and fluffed up. She collapsed about 8 hrs. later and we had to put her down 24 hrs. after that. I started Corid in their water when I saw her being lethargic but don't think she took in enough to stop it if it was cocci. I'm really not sure what got her as they'd all been healthy to that point. They're now 17 1/2 weeks old and have been off medicated feed for several weeks. They underwent a full dose of Corid in the water when the one died, about 2-3 weeks ago. All are acting fine, no one is lethargic, no one is fluffed up, all are eating. But I found a bloody poo this morning. With the little "clumps" that are in it, I think that it's shed lining. But, I'm gun-shy and unsure after losing one girl a few weeks ago and would appreciate other opinions. The chicks are now co-mingling with the "big girls" and their diet has changed a bit. They're now getting some veggies from the garden, sunflower seeds, crimped oats. Don't know if a change in diet would have any impact. Thanks for any/all help!
