Poor little Buff is lethargic, seems cold, puffed up. She is in with 4 others same age and they seem fine. I moved them a few days ago from brooder to their own room in coop away from Big's. They've from Priviett, on Medicated starter, Merek vacc but not Coccyvac. I started Corid in water for all 5 and a drop in little Buff's mouth yesterday. I don't see bloody poo..... Unfortunately before I suspected Coccidiosis, I gave everyone some Nutridrench. Took away when I started the Corid but I bet that canceled it out for day. Is there anything else I should be doing? I've wondered why I was so lucky to never have any of this issues over the years yet read how common they are. It's now my turn..... TIA for any advice
