Last week I started treating my chicks for Cocci based on the symptoms and advice from more experienced chicken owners on BYC. I bought Corid. There was only one kind at Tractor Supply, so it didn't occur to me to verify that it was safe for chickens. It actually says bovine on the package. Then I read on a thread about someone getting Corid from a vet that was specifically made for chicks and hens. Am I hurting my girls by giving them the other? I mix 1 1/2 tsp of powder per gallon. I hadn't treated my big girls since the chicks are in a separate pen. Then yesterday I noticed a couple of them acting "off" so I decided to treat them, too. I lost one of my bigger girls this morning. The other two looked pretty out of it this morning and I figured it was only a matter of time. But when I came home just now, they were both up and around. Not exactly energetic, but I have hope. My 2 hens that are actually laying, are showing no symptoms, but they are drinking the treated water. Are their eggs safe to eat? Should I toss them and wait until they're off the medicine? My beautiful rooster is one of my sickies. His comb is kind of wonky. Flopped over and sort of turning purple. Is this a normal part of the sickness? Is there a way for me (without digging up a body and taking it to a vet) to know for sure that it's Cocci I'm dealing with? I'd hate to lose any more if I take too long figuring things out. Symptoms: Not making any noise No energy Roo was holding his wings out funny on the perch One of them has blood in his poo. Could be more than one. Not sure. The one that died was having problems with balance/jumping on the stump. Right before she died she couldn't stand up. Not sure if it was lack of energy or balance. She just laid there not moving even when we nudged her.
