Thanks for that video, it's in my bookmarks now for future reference, much food for thought.
Here's a question about salpingitis vs internal laying, if you don't mind. For clarification in my mind: if the infection/mass/egg matter is in the oviduct (which would be why some birds pass lash eggs) it's referred to as salpingitis and an infection/inflammation is the root cause. And if the egg material is deposited outside the oviduct somewhere else in the abdomen then it would be referred to as internal laying (and the mass formed still looks like lash eggs, but would not be passed) and the deposit of the egg matter causes the infection, so a reproductive malfunction is the root cause. Both generally having the same outcome. I hope that is all said in a way that makes sense. Are those accurate assessments/statements? I'm just wondering for accuracy sake, I don't want to give bad or inaccurate information to anyone, and for my own knowledge in actually understanding both conditions, and referring to the correct one. Appreciate any thoughts.
