sex determination

Hello, my pets decided to have babies. I am very curious about their color mutation. Parents are what I think a yellowsided dilute and a pineapple (I will attach pic). Three of the babies I think they are like dad (yellosided dilutes) and one looks like a normal green cheek. Is this possible? No...

Right, so recently, I bought myself a third budgie bird (couldn't help myself!). He was said to be a male (three months old), but upon closer examination, I saw an anomaly! He has a deeper blue colour around the bottom edges of his cere, which fades into a really light, almost pastel, green...

My lutino tiel is just over a year old. At first we thought she was a boy, but because of her lack of tuneful singing (skipping record yapping) we now think she's a girl. However the other day, Tango discovered masturbation. Then I realised this could be a way to sex her(/him?) Tango has a...
