It's really hard to know, The only solution really is DNA testing. You can also tell by their personality, they say Females are a bit aggressive sometimes and male birds are more chirpy. I don't know if this is true but they also say you can tell by the colour of their eyes, Females have red eyes whilst males have orange or brown eyes. I have an olive Rainbow lorikeet, I wanted to know what gender he was but I decided he is male because of his personality.
Unless the bird has been privately bred by a registered breeder who has placed a leg band on the bird, there is no way to tell a rainbow lorikeet's age. There are no physical changes as they mature once they already adult birds.
maye you count how many years you re bird has been and count years by 5 s
Look At there eyes an if they are completely black they would be about 2-5 months old and if they have just normal eyes they are older
