Thanks for this. I will read it. I had two in a short period of time die from ovarian cancer (confirmed by necropsy). One I actually had euthanized once I felt she probably had it.Wonder why we hear of so many chickens having cancer ? An edifying read regarding ovarian cancer in high production hens.
