Hello everybody! My first nest hatched on march 20th.  3 Budgies out of 4 (from 5 eggs) survived.  Now that the little ones are big enough to be taken away from the parents I would like to be sure about the gender.  (I'd like to keep a female)
Here are some pictures of the 3 budgies:




It's my first time to sex birds, but as far as my knowledge goes I'd put my money on 2 males and 1 female.  The yellow one in the middle (of picture with all three) is the female.  Tell me I passed the test plz!
Thx in advance!
EDIT: moved the pictures into an album, sorry Tielfan that moving around broke your post now, but I fixed mine (I hope)
