I gave my chick honey water and a drop of Drench and put it under a heat plate. Did it again and in a couple hours it was ready to put back with mom. That was day before yesterday and it’s running around happily.Oh gosh, I am so sorry she is struggling! I have never had an issue using Corid. Its a pretty harmless substance, blocking Thiamine from being absorbed and Coccidia die. I wouldn't use any baking soda as its loaded with sodium, too much. Sugar is good as is egg. Im not sure what else you can do, I kind of doubt its the Corid but it could be. There is a molasses flush that might help but I've never used it. You might start a thread in our Emergency forum and tag @azygous She is really knowledgeable about using flushes and diagnosing stuff.
