Hi! A few months ago my hen died from a tumor in her oviduct. The vet told us that surgery could work, but that it was very risky. We chose not to do it, but since cancer is so common I’ll definitely have to deal with it again. There isn’t much on the internet about surgery other than this article https://cvm.ncsu.edu/alice-the-chicken/ Have any of you had the surgery done for your hens? Did it work? Thank you!
