If you use some sort of UV/Full-spectrum light set-up with your birds, what do you use specifically? (length of time per day, type of fixture and bulb) Have you noticed any improvement/change in behavior, feather condition, etc? I suspect the vast majority of grey owners don't mess with it and their birds do fine; also heard that it's a near necessity. Also worried that most so-called "avian UV bulbs" are really re-purposed reptile lights and are much too strong for close proximity use.
