Yesterday I bought my first one... a hen.
After purchasing it I went and talked with Lorraine from ladygouldian.com about the blues. She told me that she has absolutely no luck with them. She saidd that they are "weak" birds and require some extra care. She said something about because of the color their body doesn't absorb beta cara...something....

Does anyone out there have blues, how old are they and are they most difficult?
I really just wanted it to put into my aviary for color. I don't care if it breeds as I do not have a blue cock out there so no problem if it picks a mate.
Do they need anything different from the others?
I really respect Lorraine, but she was someone negative about them and I wondered if I had made a mistake.
I know poohbear had some and hopefully he will chime in here.
