My RIR died suddenly 2 weeks ago and we just got the necropsy report back from Davis and it says this: Diagnosis: System E. coli infection (Colibacillosis). Histopathology: Oviduct and peritoneal cavity. Severe caseonecrotizing fibrinous subacute salpingoperitonitis with intra-abdominal egg; E. coli isolated What I take that to mean is the infection killed her but what I can't seem to find online anywhere is what is the best way to make sure the other two chickens don't get it as well? And to prevent it in the future. Does anyone know? thanks!
