i have two cockatiels. i knoe that one is definately a male. the other one who is about 5 or 6 years old has ALL the characteristics of a females it but has never layed an egg. my two cockatiels were also mating during the mating season and made a nest out of sticks and grass. is it possible that my bird is a female but never layed an egg if he/she is could she start to lay eggs at this age? thanx
