ok... about 3 weeks ago my brooder chicks contracted cocci. I don't know how but they did. At the time i had 2 brooders running and both brooders managed to get it. Maybe because I wasn't washing my hands in between brooders i guess? but anyway... I treated them with 9.6% liquid corrid right away. I also ended up treating my outside birds because there were some bloody messes up at the coop so all 90+ ended up being treated. thankfully all of them accept for one survived. We got soooo lucky! That being said about 4-5 days after I stopped the medicine one 2 week old chick had a seizure and died. It was a really hot day and i thought it may have been because of heat stroke. 2 days later another chick the same age had a seizure and died. So I began to get worried that maybe I had done something wrong during treatment. They didn't all seem to be cycling at the same time so i treated for 10 days instead of 7. was this a bad thing to do? a few days later one of my 6 week old silkies had what i thought was a stroke because it couldn't open it one eye and its wing and leg were very droopy on the same side and its cherps were very muffled. within an hour it began to have seizures every few minutes but it survived 4 seizures before my husband was able to put it to sleep. The poor chick was miserable and it couldn't stand or walk and its neck and head pulled back over its body so it looked like it was trying to tuck its head under its wing but its neck was so stiff that i couldn't even correct its head! it was bizarre! So i started doing some reading and found out that cocci can cause neurological problems in cattle and dogs. I didn't find anything saying that this could happen to poultry but it makes sense based on whats been happening. has this ever happened to anyone else? should i be looking into other things? what is going on with my birds?! Then today I lost another chick. This time there was a lot of blood. Not so much the typical cocci poops but just blood like it hemorrhaged and it happened quickly. There has been no blood since treatment stopped and now today I found it dead within 10-15 minutes of giving them fresh water. Can someone please help me?! I'm going crazy over this.
