I think everyone knows how I feel about micro-chipping. All of my pets are chipped but my canary, for obvious reasons, he is just too small and is not tame like my parrots. Besides Cappy, the canary would survive outside no problem. I know, that if I lost one of my parrots and someone found him/her that I can easily identify my companions. As for pain or discomfort, I also had all my children given their shots for polio and whatever, and it did hurt, but they survived the shots and were/are safe from childhood diseases as are their children. Micro-chipping is a personal choice that we must decide on ourselves.
