So just a question are cx extra supseptable to cocci? I let my chicks out all 50 and now the 26 cx are dropping like flys I think its cossi when I get a chance I'm gonna buy some corid 9.6 can I/ should I treat all the remaining cx? Just FYI the other chicks are a bit older ruffly two months old I believe and the cx are closer to 3 weeks to a month but none had gone outside till like four to five days ago
