Two more of the white Leghorns started acting ill... one vomiting up water every time she’d drink. I separated them from the rest. Both lethargic. Was hoping Corid and electrolytes were helping... seemed to be. And tonight... another one dead! Diahrea... around. If Corid isn’t helping, what else can I do!? What would strike and kill SO fast!? I mean, if they were gonna die so quickly, shouldn’t I have been seeing large amounts of blood and really sick chickens for a couple days? This seems to have come on fast!
