Dirty cockatoo?

[Cstone01]

Hello, I have A question about our major Mitchell, We have had him for four years and he’s always dirty. I’ve never had a bird before that doesn’t seem to care about what’s on him. you know how baby birds have a dirty face because they’re not aware enough to clean off and they’re being fed formula? He always Gets whatever he’s eating all over his face. He also slides down his play stand and gets poop on his back or in his crown and then rolls around in it. I’ve been around a lot of birds and they usually fastidious cleaning them selves, He doesn’t seem to care. He’s 4 1/2 years old at this point I’m pretty sure he’s gone through puberty and I thought he would’ve grown out of it right now, I used to think it was because he was a baby. Should I be concerned?

My husband gave him half a pomegranate once and he just climbed into the thing and he will StainEd for almost 2 months, he gets in the shower every morning with my husband and we try to get whatever’s on him off, I’m just worried that it implies something else is wrong with him. I avoid giving him prickly pear, pomegranate a lot of food because he just gets it all over his face.

Also, I know this is probably anthropomorphizing him but whenever he’s eating super messy our Alexandrian looks at him like he is crazy like the other bird knows there’s something wrong with him almost.
