The concern I have is that I see too many people follow all of the typical recommendations regarding no touching, lighting, food, exercise, rearranging the cage, providing no nesting materials and on and on, yet there is absolutely no result. On the flip side, there are plenty of us that do all the "no-no's", yet don't have hens that lay eggs at all. So there is something more to this stuff....
Too often I see on other boards especially an insinuation that there must be something missing... perhaps the person is not really following all the recommendations as closely as they should, or the hen would not be still laying! But that just is not the case. Especially when you see time and time again that same suggestions, and time and time again people saying they have tried everything suggested and still the hen continues to lay. That tells me there is something the avian community is missing, and it makes sense. It is natural for us to think we know and have all the answers, but if it were that simple to stop the laying cycle, then it would be easy enough to reverse that and increase the laying cycle, thus assuring ourselves that many of the parrot species that are endangered would quickly go into the non-endangered list. I think about that a lot... because if we could do things to stop laying, then reversing those things would increase laying and assure ourselves that endangered species could be protected. Obviously, it is not that easy. So I really feel for those in a situation where they have done everything the avian community recommends and have not realized a resulting improvement in the situation. This is true whether it is simply the hormonal behaviors that we have difficulty addressing, all the way up to chronic egg laying and egg binding.
