Oh, cool I didn't know they could change genders! I've had my BP for a year and haven't seen it lay an eggs so i've been guessing a male but i'm really not sure.Can't really tell with the bp until he/she drops the goodies. But a female will start nesting before laying eggs. Fire mouth too young to tell? Hasn't colored up but I'm not a meeki expert.
One of my parrots changed gender 9 months ago (Kong).
