First let me disclose that I am VERY inexperienced at raising chickens so I need some guidance. I have two eight week old Sussex that seem to be sick. On Thursday I noticed some bloody stool in the brooder and my 2 sick chickies were listless and hunched down with fluffy unkempt feathers. Of course I immediately consulted Google and determined that it was probably coxy. Since then they have been drinking nothing but water containing the Corid Soluble Powder. The chicks are still alive and their condition does not seem to have improved. Based on what I have read they should either be dead or better by now??? Maybe I miss diagnosed? HELP!
