Blood Parrot Changing Color

[DirtyHarry]

I've had 4 juvinile BPs for about 2 weeks now, 2 are black and 2 are orange with black markings (not sure if it's the disease or not). Over the past few days one of the orange BPs has been losing the black markings and is now almost a solid orange color, actually looks better now. Also another black BP is starting to get orange coloring. What is the cause of this and will they be constantly changing color as they grow?

BPs normally start out life as that darker colour and turn orange as they grow

Ya, it's normal. My little guy used to be black/ yellow, but now he's almost completely yellow!
