Brandon, you need to learn to do research on your own whenever you question or don't know about something somebody else tells you instead of asking questions in a forum that might be answered by people who know nothing. I am not scolding you, mind you. I know that you like to know as much as possible about your birds and what I am saying is that asking people who you have no way of telling whether they actually know something or not, is not the way to learn. Go to science sources and learn from them, not from pets owners.
I am going to try to make a long story short but I am also giving you links for the long version of it.
Birds have sexual organs that go dormant during the resting season (season where there is no breeding, usually the winter but, in the tropics, the wet one). When the gonads (sexual organs which, in birds, are always inside the body -not like mammals where males have them outside the body) are dormant, they are teeny tiny and even of a different color than when they are active - they don't produce or do anything, they are just there waiting. Then when the bird reaches the point of photorefractoriness (the amount of daylight hours that the bird's particular species uses to start producing sexual hormones - there are other triggers, too), the 'master' glands of the endocrine system start producing hormones which make the 'rounds and are also 'poured' into the bloodstream (for feedback to the master glands). This is what makes the teeny tiny gonads grow and start preparing reproduction. When you don't expose the bird to the different day lengths that happen in nature and keep it to a human schedule (long days and no exposure to dawn and dusk) as well as feed too much protein, the bird's body 'thinks' it's still breeding season and it keeps on producing sexual hormones way after it should have stopped. This makes the sexual organs continue to grown when, in the wild, they would have started shrinking again until they went completely dormant. This over large gonads are the cause of discomfort and even pain. I know of birds that had blood in their urine because of this and I know of birds that have self-mutilated right above the spot where the gonads would be (one of them a male quaker, as a matter of fact).
People who say "they don't think so" have not done any research about the endocrine and reproductive system of birds because if they had, they would not say that.
This is a link to a 'compressed' and relatively easy version:

http://avianmedicine.net/content/upload ... uctive.pdf This one studies the relationship between pineal melatonin (the hormone that the body produces in the dark), photoperiodism and reproductive system.
https://www.researchgate.net/publicatio ... hilippinusAs you can see, it's the number of hours of light that makes the biggest difference (that's why birds are 'photoperiodic') and, in the wild, nature has everything under control by the seasonal changes both in day length as well as the change in diet but, in captivity, things get screwed up and the birds bodies cannot keep 'attuned' to the seasons. This screws up the endocrine system (which regulates more than just gonadal growth, mind you!) and makes the birds so uncomfortable that some of them bite chunks out of their own body in desperation.
