The way corid works was explained to me in that it doesn't kill the cocci it stops it from replicating. By doing that it helps her body build up an immunity to it. She could get worse before getting better as her body fights. Its very important that she is kept safe warm and dry all water in with her and her broodermates needs to be treated and she should be given no electrolytes until after she has completed treatment as that is what corid does to stop the cocci from replicating it blocks a vitamin/mineral that the cocci needs to reproduce. I can't remember off the top of my head what one it is though.
After she has completed treatment and only then you will want to start her on an electrolyte and a probiotic pack for a week.
